Date: Mon Jun 3 23:11:59 2024 +0200 Timestamp: 1717449119 Add helpers for managing aligned memory Previously, we had two type aliases, LargePagePtr and AlignedPtr, which required manually initializing the aligned memory for the pointer. The new helpers: - make_unique_aligned - make_unique_large_page are now available for allocating aligned memory (with large pages). They behave similarly to std::make_unique, ensuring objects allocated with these functions follow RAII. The old approach had issues with initializing non-trivial types or arrays of objects. The evaluation function of the network is now a unique pointer to an array instead of an array of unique pointers.

Date: Sat Jun 1 19:58:20 2024 +0200 Timestamp: 1717264700 MCP more after a bad singular search The idea is, that if we have the information that the singular search failed low and therefore produced an upperbound score, we can use the score from singularsearch as approximate upperbound as to what bestValue our non ttMoves will produce. If this value is well below alpha, we assume that all non-ttMoves will score below alpha and therfore can skip more moves. This patch also sets up variables for future patches wanting to use teh singular search result outside of singular extensions, in singularBound and singularValue, meaning further patches using this search result to affect various pruning techniques can be tried.
