On Accelerated Random Search

SIAM Journal on Optimization, 2004
Summary: A new variant of pure random search (PRS) for function optimization is introduced. The basic finite-descent accelerated random search (ARS) algorithm is simple: the search is confined to shrinking neighborhoods of a previous record-generating value, with the search neighborhood reinitialized to the entire space when a new record is found ...

Minimization by Random Search Techniques

Mathematics of Operations Research, 1981
We give two general convergence proofs for random search algorithms. We review the literature and show how our results extend those available for specific variants of the conceptual algorithm studied here. We then exploit the convergence results to examine convergence rates and to actually design implementable methods.

Randomized Pattern Search

IEEE Transactions on Computers, 1972
A random search technique for function minimization is proposed that incorporates the step-size and direction adaptivity of Hooke and Jeeves' [1] pattern search. Experimental results for a variety of functions indicate that the random pattern search is more effective than the corresponding deterministic method for a class of problems with hard ...

Hyperconical Random Search

Journal of Dynamic Systems, Measurement, and Control, 1972
The rate of convergence of a multidimensional random search is found to improve when the search region is restricted to a directed adaptive hypercone. The convergence properties of the hyperconical search algorithm are investigated and the scheme is applied to the problem of identifying twenty-two constants of a given chemical reaction from measured ...

Random Search Strategies

2013
A search is defined as the action to look into or over carefully or thoroughly in an effort to find or discover something. Searching is a universal behaviour of a broad range of organisms, from bacteria to whales. In a foraging process, the search is only one component among others [1, 2].
