Hi, I am finding a solver to find minimum value of objective function.
My problem includes linear problem, nonlinear problem.
I was used 'ga' to solve my problem. The format I used is
x = ga(fun,nvars,A,b,[],[],lb,ub,nonlcon,IntCon).
As the format shows, I find optimal integer x to get minimum of objective function with predefine lower bound and upper bound. I used 'A*x<=b' to solve the linear problem. 'nonlcon' to deal with nonlinear problem.
Besides, I still want to apply linear equalities by using Aeq*x=Beq. However, 'ga' cannot returen interger x by deal with with linear inequailities, linear equalities , nonlinear problem with predefined lower and upper bound.
Is there any solver could solve it?

MATLAB can not deal with this in current version
I think you can use yalmip and call "Bonmin" for free.
