Item Command generation by tree search in artificial intelligence(Texas Tech University, 1988-12) Nelson, David LeoInvestigation is made into treating the noncausal open-loop command generator for a totally automatic controller of the TAFCOS-type as a tree-search problem in artificial intelligence. Discussion is given of earlier dynamic-optimization and optimal-control approaches. It is the purpose of this work to create a software bed for achieving, in a command generator, heuristic open-loop control actions similar to humans, and thus to relieve downstream "ignorant" closed loop controllers of responsibility for dealing with large errors. Emphasis is on an "Edisonian"—in contrast to a "Newtonian"—approach. Appendices contain a simple Riccatiequation solver, two different search prototypes in BASIC, and a more general tree-based command generator in C, with a Users' Guide.
