'''Diep''',<br/>
a private chess engine by [[Vincent Diepeveen]], written in [[C]]. The development started in 1994, and so far stopped in December 2012 <ref>[http://www.talkchess.com/forum/viewtopic.php?t=66417&start=23 Re: Diep 2.0] by [[Vincent Diepeveen]], [[CCC]], January 26, 2018</ref>. Since 1999 Diep performed a [[Parallel Search|parallel search]] on [[SMP]], and later on [[NUMA]] multi core systems, and occasionally on Super Computers but unfortunately without too much support for testing. Diep's most successful year was 2004, when Diep won the [[DOCCC 2004|Dutch Open Computer Chess Championship in 2004]] <ref>[http://oudzuylenutrecht.nl/diep-nederlands-kampioen-2004/ Diep Nederlands kampioen 2004!] by [[Vincent Diepeveen]], [http://oudzuylenutrecht.nl/ Schaakclub Oud Zuylen Utrecht] (Dutch)</ref>, and won the Bronze Medal at the [[WCCC 2004|WCCC in Ramat Gan]] <ref>[http://oudzuylenutrecht.nl/wk-2004/ Diep derde op het WK 2004!] by [[Vincent Diepeveen]], [http://oudzuylenutrecht.nl/ Schaakclub Oud Zuylen Utrecht] (Dutch)</ref>. Diep spawns [[Process|processes]] for its parallel search. Due to its enormous chess [[Knowledge|knowledge]] implemented in its [[Evaluation|evaluation]], Diep was not a fast but knowledge based searcher.

Diep is without doubt the strongest chess analysis program in the world at infinite level (few hours a move). The longer you allow it to analyse the better the move it will produce, something which is uncommon for most other chessprograms, caused by the enormeous chessknowledge in Diep, which is at the time still considerably growing every month (and decreasing the Diep searchspeed).

==1997==
Diep is a classical chess playing program with this exception that I try to incorporate as much chess knowledge as possible. This is hard work, but in the end I hope it will give Diep a lot.
==1999==
Started winter 1994 with DIEP. But now i'm busy with this experimental parallel program, it's called DIEP. Still using the same huge evaluation, from which as far as i know it's the most extensive chess [[Evaluation|evaluation]] that any chessprogram contains (although mainly [[Middlegame|middlegame]]/[[Opening|opening]] heuristics).
The search of DIEP is however very very [[Selectivity|selective]] currently. I plan to join [[WCCC 1999|Paderborn]] with a complete new search. Not only parallel, but it's closer to [[Best-First|best first search]] than the depth limited [[Alpha-Beta|alfabeta search]], although it's still using the [[Iterative Deepening|iteration]] to expand nodes.
