Hi,

I want to send Gurobi an initial solution. It is also feasible to all lazy constraints that will be added. What should I do to let Gurobi accept it?

Thank you!

  Hi,

  You can provide an initial solution to Gurobi using a MIP Start. Please see How do I use MIP starts? for more information.

  However, please note that it is possible that your MIP start might not produce a new incumbent. In other words, it is possible that Gurobi has found a better solution by the time your MIP start has been processed or that the solution you provided is infeasible due to numerical issues. This is explained more in detail in this article.

  Best regards,

  Elisabeth
