Hallo, Is there a way to tell the table hashing function to ignore a field of a define-type'd value? I am writing a function for alpha-beta searching, and I'd like to use a cache to avoid re-searching previously calculated positions. So I have defined the type: (define-type node id: d7aba792-963c-41c9-b1fd-e5e26590ab34 seq ply move value ; cached value of evaluation function, ; not full search value (board unprintable:)) I need that the field 'move' be ignored by the hash function for equal?. Is that possible? Cheers, -- -alex http://www.ventonegro.org/
