MATLAB: How to make the output to be only the multiples of 10 using ‘intlinprog’

intconintlinprog

So I'm using 'intlinprog' to find the optimal value for 20 variables, including lb, ub, ueq and eq.

'intcon' has been set for variable x#17 ~#20 since those four must be integer.

My question is, if I want variable x#20 to be only in a multiple of 10, when the range is 0~50, i.e. x #20 = [0, 10, 20, 30, 40, 50], how should I add a new constraint to satisfy my needs?

in your formula and constraints multiply x20 by 10 everywhere it is used, but constrain it to be integer 0 to 5

Probably the easiest way is to set ‘x0’ appropriately and then bound ‘x(2)’ to be 40:

x0 = [20 40 20];
lb = [0 40 0];
ub = [100 40 100];
fun = @(x) x(1)+x(2)+x(3);
x_min = fmincon(fun,x0,[],[],[],[],lb,ub)

No. This would be a variable that both continuous AND discrete. You can have one or the other but not both in the same variable.

Just solve the problem twice.

1. Solve it for x==0.

2. Solve it where x is bounded in the domain [60,100].

Take the better solution. Simple.
