Re: [ojAlgo-user] Integer solver

[Francisco V. <fra...@gm...>]

The variables are binay and the X_111_19=-16
Also exits the folowing restriction: sum(X_i_j) = 1
The variables with problem are X_111_j, the variable X_112_j are ok.
The result state are: OPTIMAL 295.5

This is a print of variables after solve

0 <= X_111_0: 0 (6.6) <= 1
0 <= X_111_1: 1 (5.8) <= 1
0 <= X_111_2: 1 (5) <= 1
0 <= X_111_3: 0 (4.2) <= 1
0 <= X_111_4: 1 (3.5) <= 1
0 <= X_111_5: 1 (2.9) <= 1
0 <= X_111_6: 1 (2.3) <= 1
0 <= X_111_7: 1 (1.9) <= 1
0 <= X_111_8: 1 (1.5) <= 1
0 <= X_111_9: 1 (1.2) <= 1
0 <= X_111_10: 1 (0.9) <= 1
0 <= X_111_11: 1 (0.7) <= 1
0 <= X_111_12: 1 (0.6) <= 1
0 <= X_111_13: 1 (0.6) <= 1
0 <= X_111_14: 1 (0.8) <= 1
0 <= X_111_15: 1 (1) <= 1
0 <= X_111_16: 1 (1.4) <= 1
0 <= X_111_17: 1 (2) <= 1
0 <= X_111_18: 1 (2.8) <= 1
0 <= X_111_19: -16 (3.6) <= 1

0 <= X_112_0: 0 (7.1) <= 1
0 <= X_112_1: 0 (6.1) <= 1
0 <= X_112_2: 0 (5.3) <= 1

0 <= X_112_6: 0 (2.6) <= 1
0 <= X_112_7: 0 (2.1) <= 1
0 <= X_112_8: 0 (1.6) <= 1
0 <= X_112_9: 0 (1.3) <= 1
0 <= X_112_10: 0 (1) <= 1
0 <= X_112_11: 0 (0.8) <= 1
0 <= X_112_12: 0 (0.6) <= 1
0 <= X_112_13: 0 (0.5) <= 1
0 <= X_112_14: 0 (0.5) <= 1
0 <= X_112_15: 0 (0.6) <= 1
0 <= X_112_16: 0 (0.8) <= 1
0 <= X_112_17: 0 (1.2) <= 1
0 <= X_112_18: 0 (1.7) <= 1
0 <= X_112_19: 0 (2.4) <= 1

If you want I tell you more details of our model.
Thanks.
