Hi all,
I am using GLPK to solve a LP problem, such as:
max Z = x1 + x2 + x3
subject to: 1 > x2 + x3
2 > x1 + x2
In the first row, the coefficient of x1 is zero and in the 2nd line the
coefficient of x3 is zero. I trid to set the constaint matrix by
lpx_load_matrix(),but got an error "lpx_load_matrix: ar[1] = 0; zero element not
allowed".
How could I formulate this problem?
BR!
