Mitigating Metaphors: A Comprehensible Guide to Recent Nature-Inspired Algorithms
This addresses the issue for researchers and practitioners in optimization who struggle to understand and relate new nature-inspired algorithms due to metaphorical language.
The paper tackles the problem of incomprehensible terminology in nature-inspired metaheuristic algorithms by providing accessible descriptions of the most cited ones from the last twenty years, and it discusses their commonalities with classical methods and future directions.
In recent years, a plethora of new metaheuristic algorithms have explored different sources of inspiration within the biological and natural worlds. This nature-inspired approach to algorithm design has been widely criticised. A notable issue is the tendency for authors to use terminology that is derived from the domain of inspiration, rather than the broader domains of metaheuristics and optimisation. This makes it difficult to both comprehend how these algorithms work and understand their relationships to other metaheuristics. This paper attempts to address this issue, at least to some extent, by providing accessible descriptions of the most cited nature-inspired algorithms published in the last twenty years. It also discusses commonalities between these algorithms and more classical nature-inspired metaheuristics such as evolutionary algorithms and particle swarm optimisation, and finishes with a discussion of future directions for the field.
