In the new engine I am writing, the >granularity will be configurable by the user, with possible values between >1/8 and 1/512 of a pawn. Here's an idea: Start searching with a granularity of (a-b)/k, and for every iteration change the granularity to the new value. The values a and b are the start and end of the search interval being searched and k is some integer constant used to tune the program (e.g. 8).
