YES! Finally found a solution to Shelf Stacker (kanubem): manubeb

I just discovered the shift-Play to fast forward option from your link on colcolpicle's page and I was replaying a few old levels to watch it super fast and randomly discovered a bug in your manubeb solution to my Shelf Stacker.  Screenshot at https://www.dropbox.com/s/k7ubiz5xztlyju0/manubeb%20bug.png.  I've played it through about 20 times and only had the one failure.

I found the problem, and solved it: lazadyr. It should indeed be very rare that the problem occurs.

The cause is actually a difference in timing between the copier and the downward pipe, which shows up in combination with a door, see cozedyb. This is a breach of the Rubicon Laws of Physics that I don't think I have seen before, and the first one in a long time.


The pipe behaves the same as gravity, whereas the copier isn't copying if there was a trapdoor below it on the previous tick....but only if the trapdoor was created from the right! gikacav

Finally managed to solve shelf stacker:
For Shelf Stacker (kanubem): defucyg

This setup would not have worked if I hadn't noticed that imagethe dozers delay the crate stream by 1 tick when they return after delivering the crate, which was needed for the next dozer to pick the correct crate.

Very elegant solution.

I had a lot of trouble with the bottom shelfs. As you can see, I had to resolve to an ugly special case solution for that.
I am eager to see your solution now, Curly!

Which reminds me, a useful enhancement would be if you could click on a Random Crate ? and paste in a pre-defined sequence for it to follow instead of having it produce random crates.  This would allow thorough "unit testing" of the various edge cases.

Having just learned about using the "S" button...

Well that sure beats trying to take screenshots at exactly the right moment.  Are there are other secret keys that do stuff?  I only knew about P to switch physics models.

Here's an example solving one of the base levels using a door key: gydinug

Here's a simpler 318 tick solution (for a cost of $1150): pigimof

For Snap (suzevyz): dimidoh

You found a faster solution than me. imageMy solution tonesih has them spaced 7 apart travelling in unison the whole way.

For Traffic Counter with Speed Limit (begisok): povyhyz

I like it.  Very clean design.

OK one more modification to this puzzle:

I don't believe that level is possible. Do you have a solution?

The level is possible in principle but I also think it's not actually possible in practice.

This cutdown version is possible (and is a massive hint towards a solution of Superluminal 2b if one does exist):

Superluminal 3 jydizoz

For Superluminal 1 (vihiduz): tokuvyx

Damn, forgot about that option.  Well done.  Try this one then:

Superluminal 2b bogedef

A new puzzle series:

Superluminal 1 vihiduz (impossible?)
Superluminal 2 hynyzin (less impossible?)

There is also a 3rd easy one but I won't post that unless nobody can do these.

For Signal to Noise Ratio (pivotis): hogiror

That was tough, very tough. I started out with one approach, but could not get it to handle all special cases (quite a view for this level). I tried another approach, but did not go anywhere with that either. Then I reverted back to the first approach again, and painstakingly got everything to work. I have no room to spare.

imageThe solution I settled on is a parallel solution: all cycles are detected in parallel, and the smallest cycle that has not failed yet is continuously selected as solution. The hardest trick was to find out which one is the smallest: the valve head of the 15 cylinder engine that forms the solution. The alternative I tried was a sequential approach: try the 1 cycle first, if that fails, try the 2 cycle, etc, with both 0 and F as special cases.

I didn't expect it to be that tough when I created it but I spent almost a week trying to solve it without success before posting it.  I'm glad you didn't find it easy.

imageMy attempts at a sequential solution always ran out of space.  I knew there would be a parallel solution but I didn't know how to build that.  I had to study yours for ages to work out how it works.  Very cool.  I even like the little bit that multiplexes the input and output streams to save some extra space.
