# The Structure and Performance of the INTERIM.2 Go Program

Walter Reitman, Bruce Wilcox

*Proceedings of the Sixth International Joint Conference on Artificial Intelligence*.

## Abstract

We describe interim variants of a Go program based on skilled human models. The program maintains a permanent., selectively-updated, multilevel network analogous to the skilled player's perceptual and cognitive representation of the game situation. Moves are chosen by a hierarchy of experts and critics operating on this network. Lookahead is a selective, goal-related process, one among many components of Go skill. After an overview of system organization, we illustrate the program's performance with three segments from actual games.
