An overview of the A architecture for optimisation problems in a logic programming environment
D.P. Rodohan, R.J. Glover · ACM SIGARCH Computer Architecture News · 1991
Search of a state space is a common function in artificial intelligence applications consuming a large proportion of the total processing time. In this paper we propose a hierarchical architecture using content addressable memory to accelerate the A* algorithm in a Prolog system and remove the associated high memory overheads.
