One of the main difficulties of applying an evolutionary algorithm (or, as a matter of fact, any heuristic method) to a given problem is to decide on an appropriate set of parameter values. Typically these are specified before the algorithm is run and include population size, selection rate, operator probabilities, not to mention the representation and the operators themselves. This book gives the reader a solid perspective on the different approaches that have been proposed to automate control of these parameters as well as understanding their interactions. The book covers a broad area of evolutionary computation, including genetic algorithms, evolution strategies, genetic programming, estimation of distribution algorithms, and also discusses the issues of specific parameters used in parallel implementations, multi-objective evolutionary algorithms, and practical consideration for real-world applications. It is a recommended read for researchers and practitioners of evolutionary computation and heuristic methods.The performance achieved by manual tuning surely depends on the expertise of the experimenter. ... In consequence, we suggest to observe the measures fhc, the MBF of a standard hillclimber, fLHSa, the average fitness of an LHS design, IƒLHSa, its standard deviation, fLHSb, ... This quantity still implies dependency of the time horizon of the experiment (the total number of evaluations allowed), but inanbsp;...
