Evolutionary annealing: global optimization in measure spaces

Lockett, Alan; Miikkulainen, Risto - In: Journal of Global Optimization 58 (2014) 1, pp. 75-108

Stochastic optimization methods such as evolutionary algorithms and Markov Chain Monte Carlo methods usually involve a Markov search of the optimization domain. Evolutionary annealing is an evolutionary algorithm that leverages all the information gathered by previous queries to the cost...

Advanced particle swarm assisted genetic algorithm for constrained optimization problems

Dhadwal, Manoj; Jung, Sung; Kim, Chang - In: Computational Optimization and Applications 58 (2014) 3, pp. 781-806

A novel hybrid evolutionary algorithm is developed based on the particle swarm optimization (PSO) and genetic algorithms (GAs). The PSO phase involves the enhancement of worst solutions by using the global-local best inertia weight and acceleration coefficients to increase the efficiency. In the...

Distributed localized bi-objective search

Derbel, Bilel; Humeau, Jérémie; Liefooghe, Arnaud; … - In: European Journal of Operational Research 239 (2014) 3, pp. 731-743

We propose a new distributed heuristic for approximating the Pareto set of bi-objective optimization problems. Our approach is at the crossroads of parallel cooperative computation, objective space decomposition, and adaptive search. Given a number of computing nodes, we self-coordinate them...

Improving differential evolution through a unified approach

Padhye, Nikhil; Bhardawaj, Piyush; Deb, Kalyanmoy - In: Journal of Global Optimization 55 (2013) 4, pp. 771-799

Only a few attempts in past have been made in adopting a unified outlook towards different paradigms in evolutionary … computation (EC). The underlying motivation of these studies was aimed at gaining better understanding of evolutionary methods … direction for improving an evolutionary paradigm for a task-specific. This paper recollects the ‘Unified Theory of Evolutionary …

Genetic Algorithms for Multi-objective Optimization: Application to a Multi-reservoir System in the Chi River Basin, Thailand

Kumphon, Bungon - In: Water Resources Management 27 (2013) 12, pp. 4369-4378

The multi-objective genetic algorithm is applied to determine the optimal operation of a multi-reservoir system in the Chi River Basin, Thailand. Two competing objective functions are considered; dam release and dam storage. The predicted values for the release and storage needed are mostly lower...

The selective pickup and delivery problem: Formulation and a memetic algorithm

Ting, Chuan-Kang; Liao, Xin-Lan - In: International Journal of Production Economics 141 (2013) 1, pp. 199-211

The pickup and delivery problem addresses the real-world issues in logistic industry and establishes an important category of vehicle routing problems. The problem is to find the shortest route to collect and distribute commodities under the assumption that the total supply and the total demand...

Costly information and the evolution of self-organization in a small, complex economy

Wilson, James; Hill, J.; Kersula, M.; Wilson, C.L.; … - In: Journal of Economic Behavior & Organization 90 (2013) S, pp. 76-76

The core idea of evolution is that order in living systems emerges from a simple process of variation and selection. In biological systems we usually understand the source of variation as best described by the mechanisms of genetics. If human social systems are evolutionary systems, however, it...
