WRT the root relaxation, I have found that Heuristics=0.5 cuts the IP portion of the solution time in about half (to get to a solution with a MIPGap < 1%).  Now, the root relaxation takes about hal...

I was trying this out today, and it is not working for me.  I cannot get the workers to start.   I have a Dell XPS 15 Intel i9 core with 8 cores (16 virtual cores) running Windows 10 professional. ...

Thanks for the pointers to the documentation, I understand what is happening and why the new variable was added, and how to make it operate the way that I want it to work!

So, I believe I have figured this out. It appears that MPSRg*blort* is a dummy variable created by Gurobi for the constraint row named *blort*.  It appears to add this variable in order to make the...
