From the CHEST documentation:
History
=======
1973 Heiner Marxen writes a "mate in 2" solver in Fortran II
1978 Solving "mate in N", written in IBM/370 Assembler.
Adding selfmate, using complex kind of TT.
1983 Complete redesign in K&R C. Another kind of TT.
1987 Holger Pause and Thomas Rakovsky join the team.
Complete redesign from scratch, K&R C. Adding the concept of
direct/indirect attacks. Name it now CHEST.
Yet another kind of TT, the most simple design is really best.
1994 Switching to ANSI C. Adding special code for 2-mate candidates.
1999 First semi-public hand out to C.A.P.
Implementing EPD mode, and going public.
Holger and Thomas studied computer science, like myself.
TT = transposition table.
