I can't remember whether I invented the name. It might have been somebody else. I was the one to create the current, concise, clear definition. I think that Robert Pauli's Logical Japanese Rules of Go use a similar term and that preceded mine. But since I travel tomorrow, I cannot verify this now.

For greedy ancient rules, Berlekamp understood the concept quite some year ago but described it very differently in a way not so useful for go players, especially since those rules are not so popular :)
