rosenbrockeval.m

用小生境遗传算法实现求解rosenbrock函数的最优值

function [val] = rosenbrockEval(sol)

[m,n] = size(sol);
f = zeros(m,n-1);
for i = 1:n-1
    f(:,i) = 100.*(sol(:,i+1)-sol(:,i).^2).^2+(sol(:,i)-1).^2;  %calculation of Rosenbrock function
end;
val = sum(f,2);		%evaluate the fittness of the individual;
