Computer Go

G2.25 and G2.5, both by David Fotland, were to evolve into Cosmos, and then into Many Faces of Go.

Goo and goog wereby Peter Langston. Goog was like Goo but with the use of symmetry (meaning it played some mirror Go?)

Goanna was by Bruce Ellis.

The winner was G2.25, winning all its games.
Second was G2.5, losing only to the above.
Third was goo, losing only to both the above.
Fourth was goog, losing only to all the above.
Fifth was Goanna.

A Japanese amateur shodan at the tournament played against the entrants, and said that G2 was between 9 and 12 kyu. He played both with the parameter set to 5 and to 50, and said its level of play didn't change much.
