[ Jaglavak [1] Jaglavak,

an experimental UCI compliant open source chess engine under construction by Stuart Riffle, written in C++. Like Stuart Riffle’s earlier engine Pigeon, Jaglavak uses bitboards, and generates sliding piece attacks by Kogge-Stone [2]. Unlike Pigeon, Jaglavak performs a MCTS and uses the UCT formula to guide the selection of a node. The random playouts of the simulation phase may be distributed on CPUs, utilizing SIMD aka SSE2/4 [3], AVX2 [4] or even AVX-512 [5] instructions - or on Nvidia GPUs utilizing CUDA [6].
