Hi Alex,

Please ask how to declare a variable 0 <= x[i] <= 1?. For example, X[i]= 0.5, 0.6; 0.7, 1,...

Thank you,

Hi Alex,

Yes, thank you for helping.

The model has the Xi variable that is binary (0 or 1), because the data has 100,000 of Xi variables (i from 1 to 100,000), so the model needs to decide which some X = 1 or 0. Therefore, this is the reason that the model is working with Very long run time (over 3 days) but I don't get results.

To solve this long run time, I think that I should use Xi variable that is dvar float x[i] in 0..1 instead of binary. However, the results changed (not as expected), do you have any way to solve this problem?

Thank you,

Nguyen
