Revision as of 13:22, 25 November 2018
MadChess,
an UCI compliant open source chess engine by Erik Madsen, written in C# to run under the Windows .NET framework. It was first released under the GNU General Public License Version 3 as successor of Erik's former C# engine RumbleMinze in October 2012 [2], and features adjustable playing strength with improved algorithms since MadChess 1.4 [3] [4]. MadChess 2.1, released in February 2017 is using .NET Core, Microsoft’s cross-platform free and open-source managed software framework to support not only Windows, but Linux, and Mac [5] [6].

Description
Move Generation
MadChess applies an incremental move generation, using the C# yield statement [7] [8] [9] [10] [11] using incrementally updated list of attackers for any rank, file, diagonal, or anti-diagonal.
Search
MadChess performs a principal variation search along with transposition table, killer and history heuristic, null move pruning and late move reductions inside an iterative deepening framework with aspiration. It eliminates all reductions and lazy evaluation along the principal variation.
Evaluation
The evaluation might be lazy with respect to bounds, and otherwise uses a tapered evaluation on game phase between speculative computed middlegame and endgame scores, considering piece-square tables, mobility, pawn structure, and king safety and various piece evaluation terms.
