How to improve Bestbound?
e.g. my optimal solution for this dataset is 116. it reaches 116 within 1000 seconds but bestbound is still close to 0. Optimization part: multiplier=ub_nal * (QUARTERS[-1] - 1) + 1# spread of coef...
I used following:
prob.tune('g')
prob.controls.tunermaxtime = 100
But this is even slower. seems like stuck on even though there is tunermaxtime.
Tuner: tuning MIP problem CR_HDE_lines
baseline setting:
MAXTIME = 1500
OUTPUTLOG = 1
Tuner: starting adaptive phase 1: trying each control
