RR — An Intelligent Resource-Bounded Reasoner

  • Conference paper
AISB91

Abstract

Most of the programs developed by AI researchers, suffer from two problems: (1) they do not take into account the fact of reasoning resources are limited; (2) and they remain silent (no answer is produced) whenever a definite answer cannot be produced.

The system described in this paper combines the use of resources with the capability of producing conditional answers. A conditional answer explicitly reveals the impediments that are responsible for the lack of a definite answer.

We present RR, an intelligent resource-bounded reasoner, whose resource manipulation is flexible enough to accommodate several resource representations and resource spending strategies. Since no commitments about the way resources are spent are made a priori, the process of consuming resources can be used to model non-omniscient, non-exhaustive reasoners.

The concepts explored by RR are being incorporated into the SNePS, the Semantic Network Processing System, and so improving (1) the way human reasoning can be modeled, and (2) its interface with the outside world.
