Envy-freeness and relaxed stability: hardness and approximation algorithms

P Krishnaa, G Limaye, M Nasre… - Journal of Combinatorial …, 2023 - Springer
We consider the problem of computing matchings under two-sided preferences in the
presence of lower as well as upper-quota requirements for the resources. In the presence of …

Popular matchings in the hospital-residents problem with two-sided lower quotas

M Nasre, P Nimbhorkar, K Ranjan… - 41st IARCS Annual …, 2021 - drops.dagstuhl.de
We consider the hospital-residents problem where both hospitals and residents can have
lower quotas. The input is a bipartite graph G=(ℛ∪ ℋ, E), each vertex in ℛ∪ ℋ has a strict …

Matchings, critical nodes, and popular solutions

T Kavitha - 41st IARCS Annual Conference on Foundations of …, 2021 - drops.dagstuhl.de
We consider a matching problem in a marriage instance G. Every node has a strict
preference order ranking its neighbors. There is a set C of prioritized or critical nodes and …

Critical relaxed stable matchings with two-sided ties

M Nasre, P Nimbhorkar, K Ranjan - International Workshop on Graph …, 2023 - Springer
We consider the stable marriage problem in the presence of ties in preferences and critical
vertices. The input to our problem is a bipartite graph where and denote sets of vertices …

Balancing Matching of Two-Sided Agents with Adaptive and Fair Instability

PR Saha, S Choudhury… - 2023 IEEE Symposium …, 2023 - ieeexplore.ieee.org
The concept of stable matching is substantially used in bipartite graphs with individual
preferences of the vertices. The existence of stability restricts the weight and size of the …

How good are popular matchings?

M Nasre, P Nimbhorkar, A Rawat - arXiv preprint arXiv:1805.01311, 2018 - arxiv.org
In this paper, we consider the Hospital Residents problem (HR) and the Hospital Residents
problem with Lower Quotas (HRLQ). In this model with two sided preferences, stability is a …

Popular critical matchings in the many-to-many setting

M Nasre, P Nimbhorkar, K Ranjan, A Sarkar - Theoretical Computer …, 2024 - Elsevier
We consider the many-to-many bipartite matching problem in the presence of two-sided
preferences and two-sided lower quotas. The input to our problem is a bipartite graph …

Pareto optimal and popular house allocation with lower and upper quotas

Á Cseh, T Friedrich, J Peters - arXiv preprint arXiv:2107.03801, 2021 - arxiv.org
In the house allocation problem with lower and upper quotas, we are given a set of
applicants and a set of projects. Each applicant has a strictly ordered preference list over the …

[PDF][PDF] Min-Cost Popular Matchings in a Hospitals/Residents Instance with Complete Preferences

T Kavitha, K Makino - hospitals, 2024 - tcs.tifr.res.in
We consider a matching problem in a hospitals/residents instance G, ie, a many-to-one
matching instance, where every vertex has a strict ranking of its neighbors and hospitals …

Perfect matchings and popularity in the many-to-many setting

T Kavitha, K Makino - arXiv preprint arXiv:2411.00384, 2024 - arxiv.org
We consider a matching problem in a bipartite graph $ G $ where every vertex has a
capacity and a strict preference order on its neighbors. Furthermore, there is a cost function …
