TL;DR

This paper introduces a Self-Regulated Swarm (SRS) algorithm that combines swarm intelligence and evolutionary mechanisms to improve dynamic optimization and environment extrema tracking, demonstrating superior adaptive speed and accuracy.

Contribution

The paper presents a novel SRS algorithm that integrates societal environmental memory with self-regulation, enhancing dynamic extrema tracking performance over existing methods.

Findings

SRS outperforms standard GAs, BFOA, and co-evolutionary approaches in speed and accuracy.

SRS can track about 65% of moving peaks traveling up to ten times faster than individual agents.

The approach demonstrates quick adaptive responses and robust behavior in complex dynamic environments.

Abstract

In order to overcome difficult dynamic optimization and environment extrema tracking problems, We propose a Self-Regulated Swarm (SRS) algorithm which hybridizes the advantageous characteristics of Swarm Intelligence as the emergence of a societal environmental memory or cognitive map via collective pheromone laying in the landscape (properly balancing the exploration/exploitation nature of our dynamic search strategy), with a simple Evolutionary mechanism that trough a direct reproduction procedure linked to local environmental features is able to self-regulate the above exploratory swarm population, speeding it up globally. In order to test his adaptive response and robustness, we have recurred to different dynamic multimodal complex functions as well as to Dynamic Optimization Control problems, measuring reaction speeds and performance. Final comparisons were made with standard Genetic Algorithms (GAs), Bacterial Foraging strategies (BFOA), as well as with recent Co-Evolutionary approaches. SRS's were able to demonstrate quick adaptive responses, while outperforming the results obtained by the other approaches. Additionally, some successful behaviors were found. One of the most interesting illustrate that the present SRS collective swarm of bio-inspired ant-like agents is able to track about 65% of moving peaks traveling up to ten times faster than the velocity of a single individual composing that precise swarm tracking system.
