Abstract

A new methodology for writing efficient programs is proposed through various examples. The basic ideas are:i) the use of the appli cative stile of programming, so that correctness of programs can easily be proved, and ii) the improvement of program efficiency by the evaluation of functions applications using concurrent computing agents.

For increasing efficiency, communications among those agents are necessary, so that redundant evaluations of common subexpressions can be avoided.

In this paper we also introduce some preliminary ideas for a theory of such communications. We call them "helpful communications". They include "compulsory" communications, which effect program correctness, and "optional" communications, which do not effect program correctness, but only program efficiency.
