Summary: [For the entire collection see Zbl 0568.00022.]
In this paper, an algorithm for solving equations in equational theories is proposed. Its correctness and its completeness are proved and an implementation called NARROWER is described. It is made by extending the software REVE. Some experiments are also presented. The algorithm and its implementation have the nice property that when the set of solutions is infinite, it can detect regularity and describes the solutions. We also try to show the connection of such an algorithm with the design of a logic programming language, the purpose of which is to solve equations.
