Check out the new article: Ecological Cycle Optimizer (ECO).

The ECO (Ecological Cycle Optimizer) algorithm offers an interesting metaphor for applying the concept of the ecological cycle to the field of metaheuristic optimization. The idea of dividing a population into trophic levels — producers, herbivores, carnivores, omnivores, and decomposers — creates a hierarchical search structure, in which each group contributes to the overall optimization process.

Over billions of years, nature has refined the mechanisms of survival, adaptation, and self-organization in living systems. These mechanisms consistently attract the attention of researchers in the field of computational intelligence who seek to translate effective natural strategies into optimization algorithms. Genetic algorithms draw inspiration from evolution, swarm-based methods from the collective behavior of insects and birds, and immune system algorithms model the body's defense mechanisms.

However, until recently, one of the fundamental processes of the biosphere — the ecological cycle, a continuous circulation of energy and matter between the various trophic levels of an ecosystem — had been largely overlooked. Every stable ecosystem contains a complex network of interactions: producers (plants) convert solar energy into organic matter; herbivores consume producers; carnivores prey on herbivores; omnivores occupy intermediate niches; and decomposers close the cycle by breaking down organic matter and returning nutrients to the environment.

This elegant system of balance and interdependence formed the basis of the Ecological Cycle Optimizer (ECO) algorithm, presented in 2025 by a group of Chinese researchers led by Boyu Ma and Jiaxiao Shi. The authors proposed viewing a population of search agents as an ecosystem, in which each group of individuals plays its own role in the overall optimization cycle.
