Abstract
:1. Introduction
1.1. The Motivation
1.2. The Contribution
- (1)
- A sine cosine algorithm for elite individual collaborative search was proposed, and SCAEICS exhibits the faster convergence speed, higher convergence accuracy, and effective escape from local optima compared to the SCA;
- (2)
- In the improvement process, the tent chaotic mapping strategy and the hyperbolic tangent function strategy are adopted, which effectively solve the defect of the randomness of the population distribution and balance the global search and local exploitation;
- (3)
- In addition, the concept of the collaborative search of elite individuals is combined with SCA and used to improve the search performance of SCA;
