How to apply termination conditions to each objective function in multi-objective model
Hello everyone, I am implementing a multi-objective model in Python, and I would like to set a time limit for each objective function. It would be best if I could set different time limits for each,...
Dear Chris,
I tried implementing it based on the code you provided, and it seems to be working fine for now.
Thank you for your help.
In future releases, it would be nice to have a feature that allows you to set different termination conditions for each objective in a multi-objective model.
In Gurobi, this feature can be easily applied as follows.
self.model.setObjectiveN(stock_out_min_urgent, 0, 15, 1.0, 0.0, 0.0, ‘StockOutMinUrgent’)
self.model.setObjectiveN(stock_out_min_OEM, 1, 14, 1.0, 0.0, 0.0, ‘StockOutMinOEM’)
env0 = self.model.getMultiobjEnv(0)
env1 = self.model.getMultiobjEnv(1)
env0.setParam(‘TimeLimit’, 30)
env0.setParam(‘MIPGap’, 0.05)
env1.setParam(‘TimeLimit’, 30)
Thank you.
Best regards,
Kiseop
