WebOct 12, 2024 · Iterated Local Search, or ILS for short, is a stochastic global search optimization algorithm. It is related to or an extension of stochastic hill climbing and stochastic hill climbing with random starts. It’s essentially a more clever version of Hill-Climbing with Random Restarts. — Page 26, Essentials of Metaheuristics, 2011.
