Toward visual constraint programming

Abstract

We present a Visual Constraint Programming Language which is based on a very simple visual syntax composed of a few basic geometric shapes that correspond to the traditional clausal (i.e. textual) syntax of Constraint Logic Programming. It is however powerful and efficient, as the main idea of our approach is to compile down the visual syntax into the clausal Constraint Logic Programming format and use an efficient CLP compiler to execute the run-time code.
