There is a deep and useful connection between statistical mechanics (the behavior of systems with many degrees of freedom in thermal equilibrium at a finite temperature) and multivariate or combinatorial optimization (finding the minimum of a given function depending on many parameters). stream endobj If the move is worse ( lesser quality ) then it will be accepted based on some probability. According to Roy Glauber and Emilio Segrè, the original algorithm was invented by Enrico Fermi and reinvented by Stanislaw Ulam . En mathématiques, l’optimisation consiste en la recherche de minimum d’une fonction donnée: le domaine d’application couvre ainsi des disciplines aussi diverses que l’informatique et la génétique en passant, entre autres, par la physiquea. 0 One keeps in memory the smallest value of … Simulated annealing algorithm is an example.
