how can i solved mixed integer linear programming using genetic algorithm in matlab

suppose , in my problems there are three variables. i want the integer output of first two variables(such as 5,7) and fractional output(such as 12.234) of the last one.

I suppose you have Global Optimization Toolbox R2011b or later. The IntCon field should be [1,2] to specify that the first two variables are integer-valued. See the ga function reference page for more details and examples, or look in the mixed integer programming section of the documentation.

If your objective function and constraints are linear, I highly recommend using the mixed-integer linear programming solver in Optimization Toolbox R2014a, rather than GA. New solver: http://www.mathworks.com/help/optim/ug/intlinprog.html
