Optimalization of chess position evaluation function

[Jlisowskyy]

Main todos:

• Check whether all move sorting table are correctly allocated, cleared or scaled, prepare some tests for them. Maybe clearing is not necessary
• Prepare and test better coef sets in short make it a better evaluation function by fitting wages
• Check for correctness of logic flow inside the main eval
• Add draw material set propagation
• There should be some mechanisms that encourages the search algorithm to trade figures in situations with huge material advantage
• Prepare full logging debug function for the eval
• Replace simple linear mobility scoring function to some more sophisticated non linear one
• Consider some bonuses/penalties for bishop based on figures on white and black fields
• Focus on King safety evaluation
• MOST IMPORTANT: Prepare some mathematical optimisation tool to tailor parameters used inside the search function

[Jlisowskyy]

There were added some templated function to the KingSafetyEval and StructureEvaluator, which if not used should be removed after writing the debug function!

[Jlisowskyy]

do something to prevent exchanging bishop for a knight to get a double pawn bonus

[Jlisowskyy]

There is a good idea to add non linear mobility points function instead of used linear grading
