CatroPOLY V1.8

Engine now able to use Book1 .ctg for WHITE and Book2 .ctg for BLACK. Therefore, you can create your own .ctg with WHITE winning games, set its Learning and Priority Analysis and also for BLACK .ctg book2 similar to book1.

My advice - use PGNTools 1.5 created by Khalid Omar to split your .pgn(s) into white winning games and black winning games. Use this .pgn(s) to create your .ctg.

Add LTC Green Patches (till 06/05/2023)

How they managed to discover leaning on ctg and priority on ctg? :o As far as I lmow the CRG format is closed source, and the best we could get was tapping into Droidfish code, but that app doesn't have the priority and learning functiona typical of the (closed source) Chessbase products.. Am I losing something?

Somebody had a technical specification for the ctg format BUT from a few years ago I believe. I'm not sure but I think the GUI ChessX offered ctg capability from a while ago. Now this and I think Khalid too now offers dual capability .. BIN and CTG.

Maybe they experimented the changes on a single move CTG book and then tried to recognize the patterns on a two moves one, then on a three moves and so on...

CatroPOLY V2.1

Adding options for user to change values of Pawn, Bishop, Knight, Rook and Queen. These values only used in endgame.cpp at the moment. I am still working of using these values in other files. However, its default values still based on SF types.h file.
