The better chess engine (than the one made 2 years ago)

NOTE: Only works on Linux! To patch, change src/search.c to not use clock_gettime or CLOCK_MONOTONIC.

built on x86, no guarantee of it working on other systems :P (at least not with comparable performance)

Engine features:

• PeSTO's evaluation function
• Iterative deepening
• Negamax with alpha-beta pruning
• MVV-LVA move ordering
• Transposition table (for cutoffs and move ordering)
• Quiescence search

Game construction:

• Bitboard-based board representation
• Hyperbola quintessence for sliding pieces
• Pseudolegal move generation
• make-unmake
• Zobrist hashing

Building

make or make main compiles the main executable, which can then be run and interacted with using a UCI tool.

make test compiles main and unit tests binary, and runs unit tests, fastchess UCI test and Ethereal perft test suite. Might take a minute. make test will install following libraries (if missing) and run tests and compile main executable: run with "make install" to avoid compilation unity testing framework, includeable like #include "lib/unity.h" (https://github.com/ThrowTheSwitch/Unity) fastchess located in ./fastchess folder (https://github.com/Disservin/fastchess)
