ASMOP: Additional sampling stochastic trust region method for multi-objective problems
NataÅ¡a Krklec JerinkiÄ, Luka RuteÅ¡iÄ, Ilaria Trombini
We consider unconstrained multi-criteria optimization problems with finite sum objective functions. The proposed algorithm belongs to a non-monotone trust region framework where ad…
