Any body get this Error before when using GA

I'm solving my optimization problem using GA. It works well but suddenly I start getting this error "Error using gaminlpcreateexitmsg Exitflag from galincon does not have a corresponding exit message."

Any body can help???

Sounds like maybe a bug. What MATLAB version are you using? Can you give reproduction code?

From the error message, it seems that you are solving an integer-constrained problem that also has linear constraints. As a workaround, perhaps throw in a nonlinear constraint that doesn't do anything, such as

function [c,ceq] = mynoop(x)
ceq = [];
c = -1;

Add @mynoop as the nonlinear constraint in ga. I don't know if this will really solve your problem, but in the absence of other information it is all I can think of right now.

Good luck,
