 +**2010-05-24 François Mauger** //(mauger snail cpt point univ-mrspint point fr)// For understanding the atomic systems we are dealing with, with T. Uzer and C. Chandre, we have been looking for periodic orbits. We have been using probabilistic metaheuristic algorithm such as the Simulated Annealing to do that. Are you aware of methods based on stochastic algorithms to find periodic orbits for Hamiltonian systems or other deterministic flows?

 +**2010-06-10 Predrag to François** We have not used any stochastic algorithms to find periodic orbits. We use methods described in chapters [[http://​chaosbook.org/​paper.shtml#​cycles|13 Fixed points, and how to get them]] and [[http://​chaosbook.org/​paper.shtml#​relax|29 Relaxation for cyclists]], and sometimes we use nearest recurrences for initial guesses, as for example in [[http://​chaosbook.org/​tutorials/​recurr.html|http://​chaosbook.org/​tutorials/​recurr.html]].
