Название: Symbolic integration
Автор: Moses J.
SIN and SOLDIER are heuristic programs written In LISP which solve symbolic integration problems. SIN (Symbolic INtegrator) solves indefinite integration problems at the difficulty approaching those in the larger integral tables. SIN contains several more methods than are used in the previous symbolic integration program SAINT, and solves most of the problems attempted by SAINT in leas than one second. SOLDIER (SOLution of Ordinary DIfferential Equations Routine) solves first order, first degree ordinary differentisl equations at the level of a good college sophomore and at an average of about five seconds per problem attempted. The differences in philosophy and operation between SAINT and SIN are described, and suggestions for extending the work presented are made.
