Variable in cost function should take only two values.
显示 更早的评论
How can i set my objective function variable to take only 0 and 1 and not anything in between? I am using ga solver and my objective function is like min(f(x))= x(1) + x(2) + x(3) with constraint that (x(1) +x(2) + x(3))*0.2=0.4. Please help

Use intlinprog instead.

You must specify how the multiple objectives have to be used. Perhaps you want to minimize the sum of the objective functions? Or give each objective a weight?

(x(1) +x(2) + x(3))*0.2=0.4 is the same constraint as (x(1) +x(2) + x(3))*2=4 which is the same as (x(1) +x(2) + x(3)) = 2 . Using the integer valued one avoids any issues of round-off due to 0.2 not being exactly representable as an integer.
working in binary formay may come handy:
L=dec2bin(randi([0 100],1,1))
uint8(str2num(L(:))')
