Sorting Integers on the AP1000
Lex Weaver, Andrew Lynes
Sorting is one of the classic problems of computer science. Whilst well understood on sequential machines, the diversity of architectures amongst parallel systems means that algori…
KnightCap: A chess program that learns by combining TD(lambda) with game-tree search
Jonathan Baxter, Andrew Tridgell, Lex Weaver
In this paper we present TDLeaf(lambda), a variation on the TD(lambda) algorithm that enables it to be used in conjunction with game-tree search. We present some experiments in whi…
Pre-fetching tree-structured data in distributed memory
Lex Weaver, Chris Johnson
A distributed heap storage manager has been implemented on the Fujitsu AP1000 multicomputer. The performance of various pre-fetching strategies is experimentally compared. Subjecti…
Evolution of Neural Networks to Play the Game of Dots-and-Boxes
Lex Weaver, Terry Bossomaier
Dots-and-Boxes is a child's game which remains analytically unsolved. We implement and evolve artificial neural networks to play this game, evaluating them against simple heuristic…
