While SQL operates with relations which are sets of rows, logic programming languages such as Logica, programming the analog of a relation is a predicate and the predicate serves as a logical ...

This paper presents a constraint logic programming model for the traveling salesman problem with time windows which yields an exact branch-and-bound optimization algorithm without any restrictive ...

Meet Primo: a physical programming interface that teaches children programming logic while they control the movements of an Arduino-powered robot. All of Primo's electronics are concealed inside ...
