Solving Bilevel Knapsack Problem using Graph Neural Networks
Sunhyeon Kwon, Hwayong Choi, Sungsoo Park
The Bilevel Optimization Problem is a hierarchical optimization problem with two agents, a leader and a follower. The leader make their own decisions first, and the followers make…
Robust solutions for stochastic and distributionally robust chance-constrained binary knapsack problems
Jaehyeon Ryu, Sungsoo Park
We consider chance-constrained binary knapsack problems, where the weights of items are independent random variables with the means and standard deviations known. The chance constr…
Using the WOWA criterion for two-stage decision making problems
Jaeyoong Lim, Sungsoo Park
The weighted OWA (WOWA) is a function that aggregates a set of values with weights assigned based on the rank and relative importance of each value. The weighted OWA of uncertain o…
A branch-and-price algorithm for the robust single-source capacitated facility location problem under demand uncertainty
Jaehyeon Ryu, Sungsoo Park
We consider the robust single-source capacitated facility location problem with uncertainty in customer demands. A cardinality-constrained uncertainty set is assumed for the robust…
