Feature Request: Access to Fixed Integer Variables in Gurobi Nodes
Dear Gurobi Team,
I hope this message finds you well.
I am conducting academic research focused on developing an exact heuristic that integrates with the Gurobi solver. As part of this work, I require access to the fixed integer variables up to a given node (i.e., from parent nodes) during the branch-and-bound process.
While I am aware that some open-source solvers such as SCIP and COIN provide this capability, I am committed to using Gurobi due to its performance and robust features. Therefore, I would like to kindly suggest considering the addition of a method that allows users to retrieve fixed integer variable information at a node level in future releases of Gurobi.
Such functionality would greatly enhance the solver’s flexibility for academic and custom algorithm development.
Thank you for your continued support of the research community.
Best regards,
Saeed Abdolmaleki
