This mailing list is for discussions about the development of GNU Go,
a free go playing program, so your question is quite off-topic. I
recommend you try your luck at the news group rec.games.go.

This question does actually have an on-topic answer. GNU Go uses the
algorithm implemented in the function is_hoshi_point() in the file
engine/showbord.c, which you e.g. can find at this URL:
