Journal ArticleDOI
On benchmarking functions for genetic algorithms
TL;DR: Experimental results on the major benchmarking functions used for performance evaluation of Genetic Algorithms (GAs) are presented, including the effect of population size, crossover probability, mutation rate and pseudorandom generator.
Journal ArticleDOI
Using SVD and demographic data for the enhancement of generalized Collaborative Filtering
TL;DR: The results show that the combined utilization of SVD with demographic data is promising, since it does not only tackle some of the recorded problems of Recommender Systems, but also assists in increasing the accuracy of systems employing it.
Journal ArticleDOI
An Experimental Study of Benchmarking Functions for Genetic Algorithms
TL;DR: The general computational behavior of two basic GAs models, the Generational Replacement Model (GRM) and the Steady State replacement Model (SSRM) is evaluated.
Journal ArticleDOI
Cognitive mapping and certainty neuron fuzzy cognitive maps
TL;DR: Through simulations, the dynamical behavior of CNFCMs is presented and the inference capabilities are illustrated in comparison to that of the classical FCM by means of an example.
Proceedings ArticleDOI
String Matching on a Multicore GPU Using CUDA
TL;DR: Experimental results on the parallel processing for some well known on-line string matching algorithms using one such GPU abstraction API, the Compute Unified Device Architecture (CUDA).
