Hello,

I'm using Julia (version 1.1.1) and JuMP (version 0.21.2), Gurobi (version 0.8.1) to solve MIP. I'm struggling to add some lazy constraints in my model. My question is how to get solution from Gurobi (is there something like GetSolution( ))? It could be better if there is a simple example about TSP lazy constraint programming by Julia...

Thank you very much and I appreciate your response!

Best,

Yue
