Hi Alessandra, Simran is off today so I'll quickly poke my head in to say yes, model.reset() is the way to go.  Riley

Riley Clement commented,
Yes I can see why this is confusing when we arrive at an answer of x = 1.0, y = 536870912000000.0 Here the variables are below 1, but if we add upper bounds of 1 to the problem then the model is d...

Hi Lukas, The default lower bound on variables is 0. If you want it to be something else you need to overwrite it with the lb argument when adding your variables. To remove the lower bound altoge...

Hi Yingku, Yes, you can embed multiple machine learning models in the same optimization model. You will find examples which embed a single ML model here. Extending to two models is straightforward...

Hi Matteo, Are you using Gurobi PWL functionality and is the PWL function continuous (i.e. do adjacent segments meet, or are they disconnected)?  Riley

Hi Farhad, Jumping in for Ronald here as this question is closely related to work I did during postgrad. The problem of consecutive run time can be formulated in a way which has a nice property tha...

Hi Shesha, Will it be guaranteed that A, B, C be integers if I have a constraint A + B + C = 17. No this does not guarantee A, B, C are integer. Defining A, B, C to be integer variables guarante...

Hi Weiqi, Perhaps this is just the result of a "typo". The attribute is UnbdRay, not UnbddRay.  Riley

Riley Clement commented,
Hi Shesha, Thanks for the detail, I understand your problem, but don't understand how restricting numbers to 1 decimal place will solve it. You have the same problem with the numbers 0.2, 0.2, 0.6...

Hi Shesha, can the solver be told to use single decimal No, you would have to achieve the desired behavior through modelling constructs (i.e. with additional variables and constraints). I wasn't ...
