以优化SVR算法的参数c和g为例，对DE（差分进化）算法MATLAB源码进行了详细中文注解。(Differential Evolution algorithm (DE) is a heuristic random search algorithm based on group differences. This algorithm is proposed by R.S and k.p. rice for solving Chebyshev polynomials. DE algorithm is also an intelligent optimization algorithm, which is similar to the previous heuristic algorithm, such as ABC, PSO, etc., which is a heuristic optimization algorithm. The DE algorithm is an optimization algorithm that I used in solving the case study of box coverage.)
