How can I convert equality constraints into inequality constraints?

I m solving a problem using ga with equality and inequality constraints and want to optimise it while using binary variables. But do not solve it with equality constraints.

But what is the P here and should we eliminate Q at end?
Q is not an unknown variable. It is an NxN invertible matrix formed from linearly independent columns of Aeq. You can identify these columns using licols.m attached. P is a matrix formed from the remaining columns.
If we convert all equality constraints into inequality constraints by this way then may be we get infeasible solution.
I don't see why you would. The reduced problem should be equivalent to the original.

Did you see the documentation dealing with equality constraints for mixed-integer optimization using ga?
