I am speaking of a program that would have multiple evaluation functions. For example, a program that does some pre-analysis of the position, then determines that the position is of "type A" (or whatever), and then sets it's evaluation function for positions of type A. Type A might be "open" positions, with more tactical information. Type B evaluation function might be for closed positions where it has information about how to manuever or break the position open, at which point it would switch back to the type A evaluation function once the position becomes "open". I am wondering about programs that have more than one function that produces the score for the position. So I do not consider a function that analyzes a passed pawn to be an evaluation function. That function aids in the overall evaluation function. So basically if a function produces the score for the position, then I consider that the evaluation function, so I supposed that an evaluation function that was only for a KBN vs K endgame would indeed qualify as an evaluation function.
