Bodo 02b
Bodo 02b:-
I did not find Bodo in the forum anywhere , I am posting a link for Bodo , but cannot find Meep anywhere.
Bodo ... an UCI compliant chess engine written by Joel Veness initially in C and with a rewrite of version 0.5 in 2005 in C++. Bodo is a bitboard program , its search relies on PVS based alpha-beta with null move heuristic , iterative deepening, IID, killer- and history heuristic, and exploits its transposition table with enhanced transposition cutoffs. The quiescence search uses SEE for pruning. The evaluation function has emphasis on attacking the king and keeping the pieces active. Evaluation 'personalities' are configurable without recompile.
Bootstrapping ... Meep...
A modified version of the tournament chess engine Bodo, Meep, was used to implement learning algorithms - the hand-crafted evaluation function of Bodo was removed and replaced by a weighted linear combination of 1812 features. Given a position s, a feature vector Φ(s) can be constructed from the 1812 numeric values of each feature. The majority of these features are binary. Φ(s) is typically sparse, with approximately 100 features active in any given position. Five wellknown, chess specific feature construction concepts: material, piece square tables, pawn structure, mobility and king safety were used to generate the 1812 distinct features. These features were a strict subset of the features used in Bodo, which are themselves simplistic compared to a typical tournament engine ... http://speedy.sh/6dkXv/Bodo-02b.7z
