I find the Mortal Coil Puzzle to be boring ... all you have to do is to partition the board into sections which have only 2 entries/exists and thus only 1-2 solutions and then combine them it seems?

Here is the code for C++ for a depth of 3 ... testing it with std::bitset. Using bitsets speeds up things dramatically. I'll now work on the weighting of the new heuristic and I'll also do some early- ...

So still no hint from you guys? Razz

It seems as if representing the board as n=$depth-1 bitsets speeds up things dramatically ...

Getting the required "flippower" of a board is a matter ...

This was "inspired" by this post about ways to hash a board game's state ... http://stackoverflow.com/a/4301869 ... but using 2-3 sequential bits to represent a tile will cost a lot of compu ...

Any hint on what you did after the 43-ish levels? You mentioned Zobrist hashing but that's not really speeding up things - does it?

I just found out that the boost library now features very efficie ...

Same goes for the OneOfUs Challenge. One of the most performant HP/HC solvers out there runs for a few minutes on the last level. Perl is at least 4-5 magnitudes slower ...

Well if you genuinely believe that the language doesn't make any difference then good luck. Try solving the Crossflip challenge with Perl on a standard computer ...

Who really cares? The site is dead and the ranking never made much sense.

The point is to improve your programming skills and your overall intelligence ... well at least the one the academic world ...

After talking to 2-3 people I can confirm that they managed to solve levels beyond 44 using a totally different approach than iteration/recursion with pruning/backtracking/early outs. I expected somet ...

I even tried using a machine with 300gig of memory and 100cpus. Precalculating a lookup table for the smallest 5-6-7 pieces and using the inc-power based early out does not seem to be enough. At leas ...

There are very performant algos out there and even binaries taking a specific input format to solve the HP/HC problem. Why re-invent the wheel when you already identified the kind of algorithm you nee ...
