Hi Matteo, Do you get an explicit out-of-memory error code with error number 10001 for the 12-day model? The log only shows that the ordering took longer for the 12-day model.   What is the memory...

Does it mean, I have to set x to be GRB.INTEGER? Yes, you need to set the decision variables to either binary or integer, depending on your application. Even I define the updated model is the sa...

Hi Muhamad, As explained by my colleague, Jaromił, in your previous post, the guarantee of an integral optimal solution provided by totally unimodular constraint matrices applies strictly to linear...

Hi, I am not sure that I fully understand your question. You can query Gurobi sensitivity information on a Gurobi variable via the attributes below: SALBLow and SALBUp: smallest and largest lower...

Thanks for the clarification. Adding the constraints $$x \geq a_i + b_i - 1$$ for every $$i$$ ensures the binary variable $$x$$ equals 1 if person $$a$$ and person $$b$$ are both assigned to table ...

Hi Summer,  I have  variable that I want to set to 1 if two other related variables are also 1 Could you specify the value the binary variable $$x$$ should assume if at least one of the connected...

Hi Nico,  There are KB articles that can guide you on how to determine which subsets of constraints are causing model infeasibility. Please check these articles and follow the instructions.  How d...

Hi Luo,  One idea is to use auxiliary binary variables $$b_1$$ and $$b_2$$ to model the following: \(b_1 = \begin{cases} 1, ~~ \mbox{if}~ A \geq D+\epsilon \\ 0, ~~ \mbox{if}~ A \leq D \end{cases}...

Hi Benoit,  I see you have already set the FuncNonlinear parameter to 1 to address nonlinear constraints using the dynamic outer-approximation approach.  The common parameters used to speed up the ...
