MATLAB: GA does not solve problems with integer and equality constraints.

binary nonlinear problemsequality constraintga

Hi,

I am working on intger (binary) nonlinear problem with (0-1), with equality constraint.

when I used the GA to solve the problem I got the following error:

"GA does not solve problems with integer and equality constraints"

How can I solve this problem, and is there any function in matlab can help or support this kind of problem (integer nonlinear problem with equality constraint)

Thanks,

Reformulate your constraints:

Dear for comparing the string you should use strcmp function.

ex.

a(1).name ='2pm'; a(2).name='SNSD'; a(3).name = '2pm';
strcmp(a(1).name , a(2).name ) % this will return 0
strcmp(a(1).name, a(3).name) % this will return 1.
