Looking For Energy Efficient Genetic Algorithms
ARTIFICIAL EVOLUTION, EA 2019(2020)
摘要
When Evolutionary Algorithms (EAs) are applied to optimization problems, two main measures are taken into account to understand their performance: fitness quality and computing time. These two values are used to compare the performance of different versions of an algorithm, different parameter settings of a single algorithm or even compare a particular EA with other available heuristics. Nevertheless, a new trend in computer science tries to contextualize these features under a new perspective: power consumption. This paper presents a preliminary analysis of the standard genetic algorithm, using two well known benchmark problems, considering their fitness quality, the computing time and also the power consumption when battery-powered devices are used to run them. Results show that some of the main parameters of the algorithm have an impact on instantaneous energy consumption -that departs from the expected behavior, and therefore affects the amount of energy required to run the algorithm. Although we are still far from finding a way to design energy-efficient EAs, we think the results open up a new perspective that will enable us to achieve this goal in the future.
