Prof. Patrick Siarry was born on May 28, 1952, in Pertuis. His research area is relatively (since 1982) new “metaheuristic”optimization such as simulated annealing, which are indicated for the so-called problems of “hard optimization” because of their ability to avoid in principle, trapping in sub-optimal solutions.This topic is multidisciplinary in nature, both by the source of the methods studied (physics, biology, ethology). Much of his work is explicitly one or the other keywords – in particular, modeling,identification, learning rule bases (artificial intelligence), control,nondestructive testing and maintaining the biological and medical engineering.
