Hi Community,   I am working on a simple team member setting model using optimizer but it keeps returning "The problem is infeasible" error.   Here is my model: - The module consist of a Nurse List and a Doctor List. It has three line items : Team, Success, and Team Up  Constrain.       Team - It is the variable for optimizer. In optimizer, it has been set to integer Min = 0 and Max = 1 Success - It is a constant value (0 or 1). It indicates whether a specific Doctor-Nurse combination is workable or not. (0 - Not Work, 1 - Work).  Team Constrain - It is the constrain line item for Optimizer.   Here is the setting in Optimizer       In Team Constrain, I did try the below:   a) Team * Success >= 1 b) Team * Success = 1 c) Team * Success <= 1   Both a and b returned infeasible error. c return success but the solution is all zero in Team line item. It is appreciated if any one of you can help or point me to the right direction.    Thanks     ... View more

Hi,   From the optimizer user guide v01, for variable section, it states the min/max configuration are optional (as below and see the attached full document). So the optimizer has been configured without min/max.     However, it flows an error when execute.     Then, I configured the Min as zero and it executes successfully. If the variable can be negative value, how should I configure it to get it run?            Could anyone help to confirm the min/max configuration is optional or not? If we don't know the range of the variables, any default setting we can use?   Thanks.          ... View more
