Enhancing Differential Evolution Utilizing Proximity-Based Mutation Operators
Epitropakis, M. G.; Tasoulis, D. K.; Pavlidis, N. G.; Plagianakos, V. P.; Vrahatis, M. N. (2011)Differential evolution is a very popular optimization algorithm and considerable research has been devoted to the development of efficient search operators. Motivated by the different manner in which various search operators ... -
Evolving cognitive and social experience in Particle Swarm Optimization through Differential Evolution: A hybrid approach
Epitropakis, M. G.; Plagianakos, V. P.; Vrahatis, M. N. (2012)In recent years, the Particle Swarm Optimization has rapidly gained increasing popularity and many variants and hybrid approaches have been proposed to improve it. In this paper, motivated by the behavior and the spatial ... -
Hardware-friendly Higher-Order Neural Network Training using Distributed Evolutionary Algorithms
Epitropakis, M. G.; Plagianakos, V. P.; Vrahatis, M. N. (2010)In this paper, we study the class of Higher-Order Neural Networks and especially the Pi-Sigma Networks. The performance of Pi-Sigma Networks is evaluated through several well known Neural Network Training benchmarks. In ... -
An integrated genetic and cytogenetic map for the Mediterranean fruit fly, Ceratitis capitata, based on microsatellite and morphological markers
Stratikopoulos, E. E.; Augustinos, A. A.; Petalas, Y. G.; Vrahatis, M. N.; Mintzas, A.; Mathiopoulos, K. D.; Zacharopoulou, A. (2008)A genetic map based on microsatellite polymorphisms and visible mutations of the Mediterranean fruit fly (medfly), Ceratitis capitata is presented. Genotyping was performed on single flies from several backcross families. ... -
Multimodal optimization using niching differential evolution with index-based neighborhoods
Epitropakis, M. G.; Plagianakos, V. P.; Vrahatis, M. N. (2012)A new family of Differential Evolution mutation strategies (DE/nrand) that are able to handle multimodal functions, have been recently proposed. The DE/nrand family incorporates information regarding the real nearest ... -

Gallopoulos, E.; Hadjidimos, A.; Kotsireas, I. S.; Noutsos, D.; Vrahatis, M. N. (2009) -
Tracking differential evolution algorithms: An adaptive approach through multinomial distribution tracking with exponential forgetting
Epitropakis, M. G.; Tasoulis, D. K.; Pavlidis, N. G.; Plagianakos, V. P.; Vrahatis, M. N. (2012)Several Differential Evolution variants with modified search dynamics have been recently proposed, to improve the performance of the method. This work borrows ideas from adaptive filter theory to develop an "online" ... -
Tracking Particle Swarm Optimizers: An adaptive approach through multinomial distribution tracking with exponential forgetting
Epitropakis, M. G.; Tasoulis, D. K.; Pavlidis, N. G.; Plagianakos, V. P.; Vrahatis, M. N. (2012)An active research direction in Particle Swarm Optimization (PSO) is the integration of PSO variants in adaptive, or self-adaptive schemes, in an attempt to aggregate their characteristics and their search dynamics. In ...
