In this note, we present a slight modification of an algorithm for the strict feasibility problem. This modification reduces the number of iterations.

Deterministic global optimization using interval constraint propagation techniques

Similarity:

The purpose of this article is to show the great interest of the use of propagation (or pruning) techniques, inside classical interval Branch-and-Bound algorithms. Therefore, a propagation technique based on the construction of the calculus tree is entirely explained and some properties are presented without the need of any formalism (excepted interval analysis). This approach is then validated on a real example: the optimal design of an electrical rotating machine.
