Efficient interpretation of Prolog programs

The paper focuses on three ideas for solving problems with writing interpreters for the logic programming language Prolog in Prolog and how to combine these ideas to an interpreter for Prolog which is both simple and efficient. The resulting interpreter system can be incorporated into a Prolog based on Warren's Abstract Machine and built mostly from existing parts of it. The interpreter has been implemented and is used in a Prolog system developed at Uppsala University.
