Upper and Lower Bounds for Randomized Search Heuristics in Black-Box Optimization [PDF]

open access: yesTheory of Computing Systems, 2004
Randomized search heuristics like local search, tabu search, simulated annealing, or all kinds of evolutionary algorithms have many applications. However, for most problems the best worst-case expected run times are achieved by more problem-specific algorithms. This raises the question about the limits of general randomized search heuristics.

Error analysis of elitist randomized search heuristics [PDF]

open access: yesSwarm and Evolutionary Computation, 2021
When globally optimal solutions of complicated optimization problems cannot be located by evolutionary algorithms (EAs) in polynomial expected running time, the hitting time/running time analysis is not flexible enough to accommodate the requirement of ...

Worst-Case and Average-Case Approximations by Simple Randomized Search Heuristics

open access: yesLecture Notes in Computer Science, 2005
In recent years, probabilistic analyses of algorithms have received increasing attention. Despite results on the average-case complexity and smoothed complexity of exact deterministic algorithms, little is known about the average-case behavior of randomized search heuristics (RSHs).

An Extended Jump Functions Benchmark for the Analysis of Randomized Search Heuristics [PDF]

open access: yesAlgorithmica, 2021
Jump functions are the most-studied non-unimodal benchmark in the theory of randomized search heuristics, in particular, evolutionary algorithms (EAs). They have significantly improved our understanding of how EAs escape from local optima. However, their

Theory of Randomized Search Heuristics [PDF]

open access: yesAlgorithmica, 2012
Randomized search heuristics such as evolutionary algorithms, evolution strategies, ant colony optimizers etc. are optimization algorithms that can be applied to a wide class of problems ranging from combinatorial to continuous optimization. They are popular in practice because they are generally easy to implement, their application requires little ...

Exponential Upper Bounds for the Runtime of Randomized Search Heuristics [PDF]

open access: yesTheoretical Computer Science, 2020
We argue that proven exponential upper bounds on runtimes, an established area in classic algorithms, are interesting also in heuristic search and we prove several such results.

Runtime Performances of Randomized Search Heuristics for the Dynamic Weighted Vertex Cover Problem [PDF]

open access: yesAlgorithmica, 2020
Randomized search heuristics such as evolutionary algorithms are frequently applied to dynamic combinatorial optimization problems. Within this paper, we present a dynamic model of the classic weighted vertex cover problem and analyze the runtime ...

On the size of weights in randomized search heuristics [PDF]

open access: yesProceedings of the tenth ACM SIGEVO workshop on Foundations of genetic algorithms, 2009
Runtime analyses of randomized search heuristics for combinatorial optimization problems often depend on the size of the largest weight. We consider replacing the given set of weights with smaller weights such that the behavior of the randomized search heuristic does not change. Upper bounds on the size of the new, equivalent weights allow us to obtain
