An efficient method for segmentation of images based on fractional calculus and natural selection
TL;DR: This paper presents two novel methods for segmentation of images based on the Fractional-Order Darwinian Particle Swarm Optimization (FODPSO) and Darwinian particle Swarmoptimization for determining the n-1 optimal n-level threshold on a given image.
Proceedings ArticleDOI
A novel multi-robot exploration approach based on Particle Swarm Optimization algorithms
TL;DR: Experimental results obtained in a simulated environment show that biological and sociological inspiration can be useful to meet the challenges of robotic applications that can be described as optimization problems (e.g. search and rescue).
Journal ArticleDOI
Effect of grooves on the strength of adhesively bonded joints
TL;DR: In this article, the influence of the macroscopic state of the substrate surface on the strength of adhesive joints was studied, and several patterns were made on the surface of aluminium substrates.
Journal ArticleDOI
Benchmark of swarm robotics distributed techniques in a search task
TL;DR: The simulated experimental results show the superiority of the previously presented Robotic Darwinian Particle Swarm Optimization (RDPSO), evidencing that sociobiological inspiration is useful to meet the challenges of robotic applications that can be described as optimization problems.
