[NeoLemmix] Which levels can be beaten with the new skills?

[Minim]

Several changes have been made to NeoLemmix within the past five years. Now with the inclusion of 10 skills in a skill bar, and that we also have 2 new skills (Slider and Laserer) to play with, I thought I might create a brand new thread instead of update the old one (Which I'm going to lock). I also remember whether we should be using the Cloner or not. I updated one of the criteria to reflect this. The results from the old thread (which can be found here) can be used as a reference point for some levels, but the setup guidelines are outdated, and some of the features aren't seen in the new NeoLemmix Player, such as Challenge Mode. Also, with the updated NeoLemmix mechanics we cannot guarantee that all solutions from the new version will be able to match the old version.

To save everyone else time and effort and also, to circumvent the lack of Challenge Mode I've gone over all the Original and OhNo levels and added 10 of each new skill to every level. If any more skills are needed let me know, or if there're any that I find, I'll reupload the levels. The downloads can be found at the bottom of this thread. The rules are similar to before:

1) Can the level be beaten with only the new skills?
2) If so, assuming an X-of-everything skillset, what is the lowest X the level can be beaten with? ^
3) How many lemmings can you lose? *

^For example, solving a level with 2 builders and 2 miners is better than solving it with 3 bashers, because you've only used any one skill a maximum of twice.

*This is a change from highest %. Since the Cloner is always available, it wouldn't be a good criterion to go for most lemmings saved, because players can just put the rest of the skills on Cloners once they are happy with the solution. One downside to this criterion however is that there is no accountancy for any lemmings lost for this engine so for the sake of this challenge please mention it!

I will also include results where Rule #3 (Lemmings lost count) prioritises Rule #2 (X-of-each skillset).

*This is a change from highest %. Since the Cloner is always available, it wouldn't be a good criterion to go for most lemmings saved, because players can just put the rest of the skills on Cloners once they are happy with the solution. One downside to this criterion however is that there is no accountancy for any lemmings lost for this engine so for the sake of this challenge please mention it!

If we're only providing 10 cloners, then this still sets an upper bound on how many lemmings can be saved.

Keep in mind that the Fencer and Shimmier are still quite new and may be vulnerable to glitches.

I'd imagine Fencer should be quite stable by now - it's been around for a couple of years now. Shimmier might still prove glitchy, although so far it seems fine.

[WillLem]

Great idea for a challenge! I was thinking of remixing original Lemmings to include only new skills; seems you've beat me to it! I'll get on playing this pack straightaway and let you know what I come up with.

Best,

-WillLem

[Minim]

Ah! Thank you, WillLem. I shall send those thanks to namida too, as he came up with the idea first. I only just saw this post after I completed the Fun levels, so you wanted to do these levels then I apologise. I'll submit them anyway. See if you can match or improve these, or if you want to, go for a new difficulty rating like Tricky. I'll probably do either Taxing or Mayhem.

So, with the update I managed to solve 28 Fun levels. 21 and 23 are still impossible even with the added Fencer. The levels I failed to match from the old thread are 13 and 24.

Replays attached for 11, 15, 19 and 22. The latter two are more of the "rough idea" kind, and may not be the final solution. 19 being how to get as much height as possible, and 22 being how to save fencers. I have saved replays for all the other levels of anyone needs them.

If we're only providing 10 cloners, then this still sets an upper bound on how many lemmings can be saved.

I think 10-of-each was just to get people started, my understanding is that the challenge allows more than 10 if a level needs that.  That said, since this challenge seems to set up to minimize X first, the better your record is in terms of X, the less cloners you'd have to artificially bump up the save count anyway.

On a related note, are there upper limits built into the game?  If we can have potentially unlimited cloners, I do wonder if we can get some crazy nuke solutions for some levels that can still work out, by virtue of having cloned a crazy high number of lemmings so some would take nearly forever to actually explode?  (You'd use the nuke as a cheat way to get the effects of bombers.)  Or perhaps using nuke as part of solution should be disallowed altogether?

====================

Maybe you want to keep it as a separate challenge, but I also like the inverse idea where we go for minimum lemmings lost first, and then minimize X.  That is, a companion record that ranks rule #3 above rule #2.

That's a great idea! Just like in Sokoban games where you can have record lowest moves and pushes in the same level, there's no reason why we can't implement a similar thing here. I'm going to add these results in the same thread and see if I can reword the OP to reflect this.

In fact, I decided to challenge myself to prove that the minimum lemmings lost challenge is different to the X-skills challenge; and I succeeded. On Fun 2 I was able to save all with 2-per skill. It's surprisingly difficult to find for such an early level! Replay attached.

You can have 0 to 99 of a skill, or infinite (you can't have "greater than 99, but finite"). Infinite cloners may cause oddities with the postview texts, and could cause game lag if you use too many of them, but there is at least one level out there which naturally contains nearly 2000 lemmings* (although likely at most about 700 or so active at any one time - though removed lemmings still exist in memory, and are still "visited" during iterating through the lemmings although only to get a "this lemming is removed? go on to the next one" check) which runs without issue.

* "Infection Channel" from Lemmings Plus VI. The preview screen states 999 lemmings, but the actual level data specifies 1998 lemmings - it's a two-entrance level where one entrance spawns zombies, and the preview screen's lemming count excludes zombies. You'll never actually reach 1998 lemmings on screen at a time because the zombie entrance is directly above water, as well as the time limit running out before all 1998 lemmings have spawned. The save requirement is only 10, so this is hardly an issue gameplay-wise.

Here are my replays, solutions and results! (see attached) I've gone for all-saves first, minimising skills second. Hopefully, this will be useful as a guide to the maximum skills required to get a 100% solution, and serve as a benchmark for people to improve on.

Please note that I decided to add original skills to impossible levels (noted below in grey), again to indicate what skills would be required to get maximum saves in these levels. For the purposes of the challenge, by all means disqualify the scores for these particular levels. I still plan to release these levels as a pack at some point anyway (with my solutions as the intended ones); so I went ahead and made the necessary changes. It's worth mentioning that, in all instances, I never needed to add more than 1 of only 1 additional skill in order to complete the level.

I always used all 10 cloners just because they were there and I wanted to save all the Lemmings, darn it! But - I never counted them in the "of each" UNLESS they formed part of the solution (and even then, the amount of cloners used never surpassed the most-used skill in any level anyway).

Original Levels: Always maximum saves (0 losses).

I haven't looked at any replays yet (haven't even installed NL on my new hard drive yet) but I wanted to reply to a couple of points quickly.

Since 10 cloners are available every time, and there's no good reason why the player shouldn't use them, I always used all 10; I liked the idea of being able to save the absolute maximum number of Lemmings every time! Therefore, I have interpreted this challenge as save maximum amount first priority, minimise skills second priority.

10 is an arbitrary number -- the levels have been saved with 10 of each just because they had to have some number, but the understanding is that this challenge aims to find the minimum N such that the level is solvable with N of each. For a given level, N may turn out to be greater than or less than 10.

It's going to be very confusing if everyone reports results in a different format, as well as giving the compiler more work, so I strongly suggest keeping to Minim's format: "N of each, lost X", even when solving the second version of the challenge, with higher savings (reduced losses) as first priority.

Have a look at my replays - it's not at all been easy to get 100% + 10 Lemmings every time, I assure you!

We don't doubt that, but the hard part is saving 100%, not assigning Cloner ten times at the end

Please note that I decided to slightly modify Fun 21 and 23 to make them possible, since it's already been established that they're impossible in the original layout.

Just because one person didn't find a solution does not prove something to be impossible!

Just because one person didn't find a solution does not prove something to be impossible!

They're impossible. The only destructive skill you have is the Fencer, there is no way to create a horizontal or less-sloped tunnel with Fencers as the only destructive skill, and the Fencer's angle makes it impossible to get through obstacles in those levels (as you'll go out the top of the level and your lemmings die).

[WillLem]

I'll be honest, it's frustrating having to reply to stuff like this when I thought I'd explained myself quite well initially, but here goes...

Since 10 cloners are available every time, and there's no good reason why the player shouldn't use them, I always used all 10; I liked the idea of being able to save the absolute maximum number of Lemmings every time! Therefore, I have interpreted this challenge as save maximum amount first priority, minimise skills second priority.

10 is an arbitrary number -- the levels have been saved with 10 of each just because they had to have some number, but the understanding is that this challenge aims to find the minimum N such that the level is solvable with N of each. For a given level, N may turn out to be greater than or less than 10.

As I mentioned in my previous post, I have used all 10 cloners because they're there to be used, and allow more Lemmings to be saved. I'm aware that the number is arbitrary, but any skills which allow more Lemmings to be saved legitimately contribute towards a maximum-possible saves record, so it's right to use them if maximum saves is on the agenda.

If the aim of the challenge is to find the minimum number of skills required, then simply discount the 10 cloners. In fact, there is no need for Minim to even do this because I specifically said that I'll only specify where I used cloners when they either allowed me to reach the required saves and/or formed an integral part of the solution.

It's going to be very confusing if everyone reports results in a different format, as well as giving the compiler more work, so I strongly suggest keeping to Minim's format: "N of each, lost X", even when solving the second version of the challenge, with higher savings (reduced losses) as first priority.

N of each what? To be honest, I don't quite understand Minim's format. Hence why I've specified exactly which skills I used. I've now updated my previous post to simply give the total number of skills, in case this is more useful to the compiler.

And again, I specifically said I didn't lose any Lemmings!

Have a look at my replays - it's not at all been easy to get 100% + 10 Lemmings every time, I assure you!

We don't doubt that, but the hard part is saving 100%, not assigning Cloner ten times at the end

I don't understand what you're saying here. I have saved 100% plus the ten cloners, i.e. if the cloners were discounted, I've saved 100%. But, since the cloners are there to be possibly saved, I have chosen to save them in addition to the 100% in order to get the maximum possible save in the level presented.

The fact that I've gone for maximum saves is just as much of a challenge as going for minimum skills/losses, because quite often the solutions require quite extensive work in order not to lose any Lemmings - check out my replays, I worked hard getting these solutions! I hope that they are useful in presenting a full picture of what's possible in this alternative version of the game.

Please note that I decided to slightly modify Fun 21 and 23 to make them possible, since it's already been established that they're impossible in the original layout.

Just because one person didn't find a solution does not prove something to be impossible!

This is a fair comment, I 100% agree! But, I struggled to find a way to solve these levels as they were initally because none of the skills allow destruction of terrain downwards, and both of these levels require this in order to be solved. So, I changed the layout very minimally to make the levels possible.

What it comes down to is this:

Which is more important for this challenge - saving the maximum possible number of Lemmings, or using the minimum number of skills? I have opted to do both, but prioritise saving the maximum possible - which basically means never using the Stoner or allowing Lemmings to die if there is another possible solution (no matter how difficult).

If my contribution to this challenge thread is a problem, I'll happily create another challenge where the point is to ONLY save the maximum possible.

Or, if the challenger is happy to accept my contribution on the premise that I am always trying to save the maximum possible, and that the reason for this is to present this data however anyone wishes to use it, then there is no issue.

Let me know.

Sorry for the rant.

Minim's "fewest lost" is better than "most saved" here, because it's independent of how many cloners you use. There could of course be cases where extra steps are needed to save the cloners (to give the most basic example I can think of, envision a level that's just a direct walk to the exit, with 10 lemmings; you can easily save 10 (lose 0) by doing nothing, but if you were given some Cloners, then in addition to assigning them, you'd have to do something to turn at least one lemming around or else it becomes lose-1), but this I suspect is quite uncommon among the official levles.

This could perhaps be resolved with a rule requiring every cloner to be meaningful, but the problem there is that "meaningful" is subjective. Is it meaningful if the cloner performs a later skill that any lemming could have performed (but in this case, you specifically get the clone to do it)? What if the cloner is used this way on a worker lemming, but it would have been possible to free a single lemming from the crowd instead? Would it count if you merely assign a destructive skill or permanent skill that has no actual real-world effect?

In general - the Cloner is not well suited to any situation where saved count matters, but the quantity of the Cloner skill is not fixed.

Why is fewest lost better? Have a look at my replays - these were not easy solutions at all! Maximum saves is a very difficult challenge.

If fewest lost is the only point of the challenge and all other contribution to this thread is simply a nuisance (which is the impression I'm getting so far ), then I'll create another thread where maximum saves is the aim. I was going to do this as a challenge anyway!

I assure you, it's equally frustrating for me when I try to help things run more smoothly and it's read as an attack, but hey, that's communication on the internet. It's hard to judge the tone of voice a post is written in, so it's easy for a small misunderstanding to lead to a big upset. I hope that won't stop us cooperating, since this looks like being a fun challenge (and it's been a long time since there was any activity here in Challenges).

N of each what? To be honest, I don't quite understand Minim's format.

Okay, I think that's the root of the disagreement, so let's go over this. The idea is to rank solutions by the highest number of an individual skill used. In other words, 8 fencers and 8 disarmers is "better" than 9 fencers and 1 stoner. The former solution would be possible with a skillset of 8 of each skill; the latter requires at least 9.

That means that although there are 10 cloners in the level file given, firstly, you can't use them freely because if you have, for example, a 2-of-each solution, you are making it worse by using extra cloners; secondly, if a level was not solvable with 10 of each, but might be solvable with a larger number of each, you are allowed to modify the level and report a solution for the larger number.

Just to be clear, I have nothing against you reporting the total number of skills used; it's just not part of this challenge as Minim originally proposed it, and so I wanted to make sure we are tackling the same challenge so as to avoid unnecessary effort.

I don't understand what you're saying here. I have saved 100% plus the ten cloners

What I'm saying is that in terms of number of lemmings lost, it's equally good to save 50/50 as it is to save 60/50 with ten cloners. So the number of lemmings lost is a better way to write up the result, because that makes it really clear for the reader how good a solution is -- especially as we get to harder levels where we might well end up going over the 10-of-each for some levels.

The fact that I've gone for maximum saves is just as much of a challenge as going for minimum skills/losses, because quite often the solutions require quite extensive work in order not to lose any Lemmings

Indeed, that was ccexplore's point -- both versions of the challenge are interesting. What I'm hoping for is that eventually we'll have a list of the best results for each level in both categories: smallest N-of-each first and minimum losses second, and the other way around.

I'm looking forward to having a go at this as soon as I have NL reinstalled

Why is fewest lost better? Have a look at my replays - these were not easy solutions at all! Maximum saves is a very difficult challenge.

So is fewest lost, because it's the same challenge. Given the same level and two solutions to it, the solution that loses fewer is the same as the solution that saves more.*

All that namida and I are saying is that reporting the solution in an "X lemmings lost" format is clearer. Yes, X = 0 for all the Fun levels, but that may not be true throughout the entire game.

*Except for Crazy 11 in DOS Lemmings with the nuke glitch. But that's not relevant here.

If fewest lost is the only point of the challenge and all other contribution to this thread is simply a nuisance (which is the impression I'm getting so far ), then I'll create another thread where maximum saves is the aim. I was going to do this as a challenge anyway!

So I just want to make clear, you are not a nuisance, this is just a small misunderstanding to which we are trying to add clarity. Please don't create another thread for the same challenge.
