Dear Riley, Many thanks for your answer as well as the provided links. It seems Gurobi uses the BigM method to linearize finally the indicator constraint. As I am not well familiar with SOS constra...

Dear Riley, Many thanks for your informative comments. The parts, either be translated to linear constraints and will be translated into SOS1 constraints are exactly what I was looking for. Could y...

Dear Riley, Thank you so much for your detailed answer. If you have a convex hull formulation then the model can be solved with an LP algorithm, you won't need MIP strategies like branch and boun...

Is there a preference to use Convex-hull reformulation instead of the BigM constraints?
進行中Dear support team, I am trying to work on a scheduling problem based on its polyhedron reformulations. For that, I would like to reformulate a BigM model into its equivalent Convex hull, (CH), for...

Linearizing factorial function
回答済みDear community team, I'm trying to write a constraint in the following form: $$(a_j * (s_j!)) / L \leq 1-\gamma$$ Where \(\texttt{a}\) and \(\texttt{gamma}\) are constants and \(\texttt{s}\) and \(...
