随着计算机科学的发展,智能优化算法已成为研究热点之一。以下是六种最新智能优化算法(LSO、SWO、ZOA、EVO、KOA、GRO)的介绍,以及它们在23个基准测试函数上的应用。
###1. LSO(Learning-based Swarm Optimization)
LSO是一种基于学习的群体优化算法,通过结合遗传算法和粒子群优化算法来实现。其基本思想是,将多个粒子群合并成一个超群,然后使用遗传算法来更新超群中的粒子。
#### 基准测试函数:
* **Ackley函数**:f(x) = -20 * exp(-0.2 * sqrt(1/n * ∑x_i^2)) - exp(1/n * ∑cos(2πx_i)) +20* **Rosenbrock函数**:f(x) = ∑[100 * (y_i^2 - x_{i+1})^2 + (1 - x_i)^2]
#### MATLAB代码:
matlabfunction f = ackley(x) n = length(x); sum1 =0; sum2 =0; for i =1:n sum1 = sum1 + x(i)^2; sum2 = sum2 + cos(2*pi*x(i)); end f = -20 * exp(-0.2 * sqrt(sum1/n)) - exp(sum2/n) +20; function f = rosenbrock(x) n = length(x); sum1 =0; for i =1:n-1 sum1 = sum1 + (x(i+1)^2 - x(i))^2; end f =100 * sum1 + (1 - x(1))^2;
