In mathematics, the spiral optimization (SPO) algorithm is a metaheuristic inspired by spiral phenomena in nature. The first SPO algorithm was proposed for two-dimensional unconstrained optimization based on two-dimensional spiral models. This was extended to n-dimensional problems by generalizing the … See more The motivation for focusing on spiral phenomena was due to the insight that the dynamics that generate logarithmic spirals share the diversification and intensification behavior. The diversification … See more The search performance depends on setting the composite rotation matrix $${\displaystyle R(\theta )}$$, the step rate $${\displaystyle r(k)}$$, and the initial points $${\displaystyle x_{i}(0)~(i=1,\ldots ,m)}$$. The following settings are new and effective. See more Many extended studies have been conducted on the SPO due to its simple structure and concept; these studies have helped improve its global search performance and proposed novel applications. See more • The algorithms with the above settings are deterministic. Thus, incorporating some random operations make this algorithm powerful for global optimization.
