Ed Klotz commented,
As you noted, the performance challenge here appears to involve progress in the dual bound (aka best bound in the node log). You have set the MIP Focus parameter to 1, which will cause Gurobi to...

Looking at the log file you provided, Gurobi spends over an hour during the root node cut loop, yet the progress in the best bound is pretty modest. And all the added cuts may add run time to the...

I stumbled onto this 6 months after the initial post. You might have gotten a faster response if you'd simplified the expression above by setting all your constraint values and your index sets to...

Haoge, Yes, your concern about scalability of the linearization approach is reasonable. In fact, if you go to the web pageI mentioned above: yetanothermathprogrammingconsultant.blogsp...
