My progress attempting to solve the Eternity II puzzle.
8th August 2007
Project status: Still not finished defining all pieces. But have all edge pieces in.
Achievements to date: Can find an edge-only solution in ~20ms, finds approx 20,000 edge solutions per second.

200 pieces defined, still not verified.

All pieces in (but not included in this version because of copyright issues). Added piece browser to solver to help me check the pieces.

Used Stephen Gryphon's notes on CRCs to check my piece definitions and found a couple of errors. All correct now - thanks Stephen.
Can now generate test boards (using Zerjillo's code). This example solves a 9x9x22 puzzle pretty quick! Some 10x10x22's can solve quickly, but some can take a while, still ong way to go to 16 :-(
