Chaos-based firefly algorithms for optimization of cyclically large-size braced steel domes with multiple frequency constraints

摘要: Abstract The success of the search in firefly algorithm is highly dependent on a good balance between exploration and exploitation. Although, basic relatively efficient; two chaotic algorithms based Logistic map (CLFA) Gaussian (CGFA) have been presented to improve FA. As numerical examples, some large-scale domes are designed for multiple frequency constraints optimization. Despite fact that these problems nonlinear, results illustrate desirable performance both obtaining lower weight having higher convergence rate.
