Paper by J A Robinson
The paper from J.A Robinson presents a formulation of first order logic, which is designed to use as an instrument for computer theorem proving program. There have other first order logic based theorem but they are mostly used for other purposes. Inference principles needs only to be sound and effective. The paper provides an inference principle called resolution principle which not human oriented but machine oriented. The formalism used in this paper in not validity and proof but un-satisfiability and refutation. They are some notations used in this paper and definitions of those are:
As J A Robinson (1965) states “Variables are u,v,w,x,y,z,u1,v1,w1….etc. Function Symbols are a^n,b^n,c^n.. if n>=0 or
