Hello community can anyone help me solve this problem please.
I have to minimize this:
F= P1*X1+P2*X2+P3*X3+P4*X4
s.t P1X1+P3X3 ≤ L1
P2X2+P4X4 ≤ L1
P1X1+P2X2=E1
P3X3+P4X4=E2
P1,P2,P3,P4,L1,L2,E1,E2 are known.
X1,X2,X3,X4 are the unknown variables, they must be binary .

Any values that satisfy your first two constraints are a solution to the problem since your objective function is constant. Substitute the third and fourth constraints into the objective function to see that this is the case.
In this small case you don't need intlinprog. Brute force is sufficient.
