Iterated Local Search (ILS) has many of the desirable features of a metaheuristic: it is simple, easy to implement, robust, and highly effective. The essential idea of ILS lies in focusing the search not on the full space of solutions but on a smaller subspace defined by the solutions that are locally optimal for a given optimization engine.

Local Search for Unsatisfiability [PDF]
Local search is widely applied to satisfiable SAT problems, and on some classes outperforms backtrack search. An intriguing challenge posed by Selman, Kautz and McAllester in 1997 is to use it instead to prove unsatisfiability. We investigate two distinct approaches.

Experiments to shed light on the best way to use Iterated Local Search for a complex combinatorial problem [PDF]
Iterated Local Search (ILS) is a popular metaheuristic search technique for use on combinatorial optimisation problems. As with most such techniques, there are many ways in which ILS can be implemented.

On the Local Convergence of Pattern Search [PDF]
The authors consider local convergence properties of pattern search as a class of direct search methods for solving nonlinear programming problems. For simplicity, only the unconstrained case \(\min_{x\in\mathbb{R}^n}\,f(x)\) is considered. Numerical tests are given.

Unsupervised Local Feature Hashing for Image Similarity Search [PDF]
The potential value of hashing techniques has led to it becoming one of the most active research areas in computer vision and multimedia. However, most existing hashing methods for image search and retrieval are based on global feature representations ...

Hybrid Gravitational Search Algorithm Based on Fuzzy Logic
Gravitational search algorithm (GSA) is a novel heuristic optimization algorithm which is used to search for the global optimal solution by iteration. However, GSA is easy to fall into local minima and convergence slowly.
