Abstract

A new method of solving Horn logic with equality, the goal-type driven method, is presented, which considers explicitly the unification operator as a goal and merged it into the resolution process. The method has the following advantages. The resolution and the unification have been integrated in a uniform way. The architectures of the inference engines based on Horn logic with equality are simplified. Any techniques of exploiting AND/OR parallelism to solve goals can also be applied to unification at the same time. The method can be used to integrate the styles of functional laguage and logic language by a uniform framework. It can also deal with infinite data structures.
