[HTML][HTML] Half-cycle: A new formulation for modelling kidney exchange problems

M Delorme, D Manlove, T Smeets - Operations Research Letters, 2023 - Elsevier
We introduce the half-cycle formulation (HCF), a new integer programming (IP) model for the
kidney exchange problem, which has life-saving applications. In HCF, a cycle (ie, set of …

New algorithms for hierarchical optimization in kidney exchange programs

M Delorme, S García, J Gondzio… - Operations …, 2024 - pubsonline.informs.org
Many kidney exchange programs (KEPs) use integer linear programming (ILP) based on a
hierarchical set of objectives to determine optimal sets of transplants. We propose innovative …
