How to Control optimizaiton's variable changing step

1 view (last 30 days)
Hi mathworks Heroes !
I was wondering if there is any way to adjust the optimized variables step changement,because i want to optimize a variable that can only change by a decimal degit (1,2,3,4,5....) .
i'am using optimization Toolbox (Fmincon)
thanks in advance

Unfortunately, fmincon does not accept integer constraints. If your problem has an approximately quadratic objective, you can try using intlinprog along the lines of this example. Otherwise, the only solvers we offer for mixed-integer nonlinear programming are genetic algorithm and surrogate optimization solvers in Global Optimization Toolbox.

Try to create a nonlinear constraint function that selects only integer values of the variables being optimized
