一个GA-PSO算法 GAPSO-share
我从网上下载了一个GA-PSO算法,试着利用GA和PSO组合的策略进行优化,结果算法很问题,效率和不错。我下载原始算法,有一个问题就是它是针对所有的设计变量上下限都是一样的,所以我对程序进行了修改与改进,现在可以处理上下限不一致的问题,同时fix了一些bug。(GA GA and PSO algorithm matlab program combined ion group
When doing optimization, first choose the GA algorithm, but the instability of the GA (or into a local optimum) it drives people crazy, even after twice the difference results can sometimes reach 30 or more, but because of time reason, I had to choose the optimal 1000, then the minimum of which the most optimal solution. Although the problem is considered solved, but will be from an academic, which makes Ben is very embarrassing. So, I downloaded a GA-PSO algorithm, try to use a combination of GA and PSO optimization strategy, the results of algorithm is the problem, efficiency and good. I downloaded the original algorithm, there is a problem is that it is the design variables for all upper and lower limits are the same, so I had to modify and improve the program, can now handle upper and lower limits inconsistencies, and fix some bug.)

MATLAB 牛顿下山法的一个小程序,原理就不详细说了。因牛顿迭代法受初值选取的限制,为防止迭代发散,对迭代过程再附加一项要求:|f(x(k+1))|<|f(x(k))|,将牛顿法迭代的结果:x(k+1) =x(k)-f(x(k))/f (x(k))和前一近似值x(k)适当加权平均做为新的改进值:x(k+1)=u*x(k+1) +(1-u)*x(k),其中u(0<>
迭代时u取1开始,逐次减半计算,直至附加要求符合为止。实例计算中x(k)=x(0)不变,只更新u和x(k+1),直至:|f(x(k+1))|<|f(x(k))|(即|f(x(1))|<|f(x(0))|),然后更新下山因子为u=1,继续以牛顿法迭代。(MATLAB Newton-down a small program, the principle is not explained in detail. Newton iteration by the initial value of the selected limit, in order to prevent additional iterative divergence, the iterative process a request: | f (x (k+1)) | < | f (x (k)) | Newton iteration Results: x (k+1) ' = X (k)-f (x (k))/f' (x (k)) and a previous approximation x (k), appropriately weighted average as a new improved value: x (k+1 ) = u* x (k+1) ' + (1-u)* x (k), where u (0 < u> iteration take successive calculated at 50 until the additional requirements found so far. examples of calculation of X ( k) = x (0) unchanged profile u and x (k+1, hungry) until: | f (x (k+1)) | < | f (x (k)) | (i.e. | f (x (1)) | < | f (x (0)) |), then profile downhill factor for u = 1, to continue to Newton iteration.)
