  Dragon is a [[Brute-Force|brute force]] program. Dragon divides the tree [[Search|search]] in two phases: full search and [[Quiescence Search|quiescence search]] ([[Captures|captures]], [[Promotions|promotions]] and [[Check|check]] for the first level of quiescence). The algorithm is the [[Principal Variation Search|PVS]] with [[Iterative Deepening|iterative deepening]]. It uses most of the known standard heuristics : [[Killer Heuristic|killer moves]], [[History Heuristic|history moves]], [[Transposition Table|transposition table]], [[Null Move Pruning|null move]] and [[Extensions|selective deepening]]. Dragon can recognize [[Repetitions|draw by repetition]] and apply [[Fifty-move Rule|50-move rule]]. It can [[Pondering|think]] on the opponent's time. Dragon uses a small [[Opening Book|opening book]] but with a variety of lines. The [[Evaluation|evaluation function]] examines the [[Pawn Structure|pawn structure]] (it uses the [[Bitboards|bitboard]] for the pawns), the position of the pieces ([[King Safety|King's security]], [[Center Control|central control]], [[King Safety#KingTropism|King tropism]], [[Outposts|outposts]], ...).

Dragon,
a Chess Engine Communication Protocol and later UCI [2] compliant chess engine by Bruno Lucas. Dragon played the WMCCC 1997 in Paris and most French Computer Chess Championship and French Programmers Tournaments. Dragon is Arena partner engine.

Descriptions

by Bruno Lucas

1997 ...

from the ICGA tournament site in 1997 [3]: 

Dragon is a brute force program. Dragon divides the tree search in two phases: full search and quiescence search (captures, promotions and check for the first level of quiescence). The algorithm is the PVS with iterative deepening. It uses most of the known standard heuristics : killer moves, history moves, transposition table, null move and selective deepening. Dragon can recognize draw by repetition and apply 50-move rule. It can think on the opponent's time. Dragon uses a small opening book but with a variety of lines. The evaluation function examines the pawn structure (it uses the bitboard for the pawns), the position of the pieces (King's security, central control, King tropism, outposts, ...).  Dragon can read, save the game in PGN format and the position in FEN format. It can be interfaced with xboard/winboard.

My future goals it's to become selective and to be able to build plan.

2003

from the Arena site in 2003 [4]: 

Dragon 4.0 is based on bitboard.  It has the same evaluations of Dragon 3.x. The search has been updated.  I removed bad extensions, especially those ones that were greedy on nodes and time.  The main differences between Dragon 4.0 and Dragon 3.x  are on search extensions, sorting of moves and test evaluations. ...
