Connect Four Hash Function: Map close elements to close hash keys?

I don't think this is possible. A good hash key (like zobrist hashing is for board games) will most likely have pseudo random properties to achieve a uniform distribution of keys in the transposition table. Having the keys of "close" positions close to each other in table contradicts this.

Here is how to modify your presumably nearly uniformly random hash function to bias it in a way that similiar board positions are somewhat likely to occur at nearby hashes.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
