Hysteretic optimization is a recently proposed heuristic optimization method inspired by the demagnetization of … optimization problems works reasonably well for the traveling salesman problem. We propose an improvement for the general scheme. …

Hysteretic optimization is a heuristic optimization method based on the observation that magnetic samples are driven … optimization is very good for finding ground states of Sherrington–Kirkpatrick spin glass systems. With this method it is possible … way we estimate error rates may be useful for some other optimization methods as well. Our results show that both the …

The partitioning of random graphs is investigated numerically using “simulated annealing” and “extremal optimization …”. While generally in an NP-hard problem, it is shown that the optimization of the graph partitions is particularly difficult … “simulated annealing” is found to diverge in the thermodynamic limit. On the other hand, “extremal optimization”, a new general …
