Ranan Banerji
Ranan Banerji worked on the mathematical foundations of AI problem solving and learning. He earned a physics doctorate at Calcutta in 1956. At Case Western Reserve, he studied game representations with George W. Ernst. Their 1971 paper sought transformations that preserve useful strategies. A 1977 joint paper examined automatic construction of a General Problem Solver connection table. His 1987 paper, written at Saint Joseph’s, developed concept learning in a logical language that grows with the learned theory. He retired in 1992 and died in 2016.

1956
A physics background
Banerji earned a physics doctorate at Calcutta University in 1956. He later taught physics, mathematics and computer science at several universities, including Case Western Reserve, Temple and Saint Joseph’s.

1971
Preserving game strategies
Banerji and George W. Ernst studied how a change in a game’s representation can preserve a useful strategy. Their IJCAI paper defines relationships between game structures and develops conditions for relating games to positional games. Both researchers were affiliated with Case Western Reserve.

1977
Constructing a problem solver’s table
Their later IJCAI paper studied automatic construction of the connection table that guides the General Problem Solver. It describes using properties of problem states that remain unchanged under selected moves, then combining those properties into a table. Banerji was affiliated with Temple. The paper describes a theoretical basis and programs developed at Case Western Reserve.

1987
Learning a growing language
At Saint Joseph’s, Banerji described an algorithm that learns logical theories while also learning the language used to express them. Previously learned concepts can help describe new concepts. The paper builds on work by E. M. Gold and Ehud Shapiro and specifies a restricted first-order language.

1992–2016
Later career
Banerji retired in 1992 and later wrote Society, Scientists, and the Spirit. He died on 9 December 2016. His AI papers address symbolic descriptions, problem-solving methods and learning.
