objective function

Maximum f=-3x 1+2x2-5x3

Constraint condition

x 1+2x2-x3≤2，

x 1+4x2+x3≤4，

x 1+x2≤3，

4x 1+x3≤6，

X 1, x2 and x3 are 0 or 1.

Enter the following command in the Matlab command window:

f=[-3，2，-5]；

a=[ 1，2，- 1，； 1,4, 1; 1, 1,0; 0,4, 1]; b =[2； 4; 3; 6];

[x，fval]=bintprog(-f，a，b)

% because bintprog is solving the minimum value of the objective function, a negative sign should be added before F.

The running results are as follows:

Optimization terminated.

x = 0

1

fval = -2

It means that when x 1=0, x2= 1, x3=0, the maximum value of f is 2.

Of course, we can also enter the following command in the Matlab command window to inquire about the usage of the 0- 1 integer programming command.
