Abstract reasoning ability is fundamental to human intelligence. It enables humans uncover relations among abstract concepts and further deduce implicit rules from the relations. As a well-known visual task, Raven's Progressive Matrices (RPM) are widely used in IQ tests. Although extensive research has been conducted on RPM solvers with machine intelligence, few studies have considered advancin...

In this paper we give a summary of the Autonomous Agent Architecture (AAA architecture for short) for intelligent agents. The AAA architecture is the result of several years of research on the design and implementation of intelligent agents that reason about, and act in, changing environments. In the AAA architecture, the knowledge about the domain where the agent is situated is encoded in Answ...

We consider here the collection of all partitions of an n-set, for fixed n, and we ask: is it possible to arrange these partitions in a list (Gray Code) so that each partition is obtained from its immediate predecessor by changing the class of exactly one element? The answer is affirmative, and we give descriptions of two algorithms which implement the method, the first recursive, the second no...
