a new meta-heuristic method, based on neuronal communication (nc), is introduced in this article. the neuronal communication illustrates how data is exchanged between neurons in neural system. actually, this pattern works efficiently in the nature. the present paper shows it is the same to find the global minimum. in addition, since few numbers of neurons participate in each step of the method,...

As a swarm-based optimization heuristic, the Ant System (AS) was proposed to deal with Traveling Salesman Problem (TSP). Classifified as constructive approach, AS inspired by ants’ social behavior.In Practice, its implementation reveals three basic variants that exploit two operating models: fifirst “natural” model, where ants move and update pheromones, consideration of distances between towns...

this paper presents a new meta-heuristic solution to find the efficient frontier using the mean-variance approach. portfolio optimization problem is a quadratic programming model and, changes to np-hard if the number of assets and constraints has increased, and it cannot be solved using common mathematical methods in a reasonable time. therefore, a heuristic or meta-heuristic algorithm should b...
