No, I am not saying hand tune mobility. I am saying, Knight with one square to move to gets one weight, and Knight with two squares to move to gets another weight. Both weights can be auto-tuned. They are independent.

I do not agree they are independent. They follow an average logarithmic pattern of increase.

It should be added further that this is the point of the exercise. Individual tuning of a parameter only tries to make up for the inadequacy of other variables, in spite of Peter Osterlund's claim that the tuning method adapts somewhat for elasticity of values. The result is an uneven curve with occasional spikes and unexplainable values.

By forcing the parameters to follow a smooth curve, other piece values can fit their curve better. The result should be that pieces will not fight with each other for control of space on the board, but adapt with each other to maximize mobility. The final test is whether there is an increase in strength. This cannot ultimately be seen by changing mobility for only one piece, but for all pieces so they can co-ordinate. Also, by forcing a natural logarithmic curve and testing its coefficients, a smaller sample size for the test set should produce a faster convergence.

This method is new (to me) but eventually it should be adaptable to all tables. The next step will be to try passed pawn values.
