An adaptive tree pruning system
Edward W. Kozdrowicki · 1968
The tree pruning system (TPS) consists of a set of commands designed for programming heuristic tree searches. This system was assembled as a pre-FORTRAN compiler similar in principle to that of FORMAC. TPS and FORTRAN IV statements are used together for writing programs. In the present implementation, each TPS command must be preceded by an asterisk (*) in the first column to distinguish it from a regular FORTRAN statement. TPS has the two-fold purpose of being a language for manipulating tree-structured data formations and also encompassing machine-learning capability.
