I doubt if anyone can measure it. Look up information theory on the web.

Another type of chess knowledge is that pertaining to move ordering. Also, non-chess knowledge to increase the efficiency of a program is another type knowledge and the one the one you appear to allude to. All of these I think they need to be considered separately. However, the one I'm most interested in is the knowledge used in evaluation. > >>How much attention should a programmer give to lowering the EBF of his program >>versus adding more knowledge? > >Just pick a single move. EBF is one. In other words, any reduction in EBF >must be smart or it may do more harm than good. Which is one of the reasons why I asked, "How much attention should a programmer give to lowering the EBF of his program versus adding more knowledge?" I think it is possible to answer my question a little bit intelligently ;-) > >>I'm curious about the different opinions programmers have on this topic.
