WebbThe key feature of simulated annealing is that it provides a means to escape local optima by allowing hill-climbing moves (i.e., moves which worsen the objective function value) in hopes of finding a global optimum. WebbSimulated Annealing is a popular algorithm used to optimize a multi-parameter model that can be implemented relatively quickly. Simulated Annealing can be very computation …

WebbSince Optim is entirely written in Julia, we can currently use the dispatch system to ease the use of custom preconditioners. A planned feature along these lines is to allow for user controlled choice of solvers for various steps in the algorithm, entirely based on dispatch, and not predefined possibilities chosen by the developers of Optim. http://www.diva-portal.org/smash/get/diva2:18667/FULLTEXT01 earth arcade mydramalist

One-stage algorithms The one-stage algorithms have one clear goal and a function returning a value of how close to the goal the solution is. Therefore, these algorithms can break both hard and soft constraints. http://www.diva-portal.org/smash/get/diva2:18667/FULLTEXT01 ctd 5.3.5.3
