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 …

Maximally satisfying lower quotas in the hospitals/residents problem with ties

H Goko, K Makino, S Miyazaki, Y Yokoi - arXiv preprint arXiv:2105.03093, 2021 - arxiv.org
Motivated by the serious problem that hospitals in rural areas suffer from a shortage of
residents, we study the Hospitals/Residents model in which hospitals are associated with …

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 …

Envy-freeness and relaxed stability for lower-quotas: A parameterized perspective

G Limaye - Discrete Applied Mathematics, 2023 - Elsevier
We consider the problem of assigning agents to resources under the two-sided preference
list setting where resources specify an upper-quota and a lower-quota, that is, respectively …

Polynomially tractable cases in the popular roommates problem

E Bérczi-Kovács, A Cseh, A Mályusz - arXiv preprint arXiv:2107.06694, 2021 - arxiv.org
The input of the popular roommates problem consists of a graph $ G=(V, E) $ and for each
vertex $ v\in V $, strict preferences over the neighbors of $ v $. Matching $ M $ is more …

Student Course Allocation with Constraints

A Utture, V Somani, P Krishnaa, M Nasre - Analysis of Experimental …, 2019 - Springer
Real-world matching scenarios, like the matching of students to courses in a university
setting, involve complex downward-feasible constraints like credit limits, time-slot constraints …

Envy-freeness and Relaxed Stability under lower quotas

P Krishnaa, G Limaye, M Nasre… - arXiv preprint arXiv …, 2019 - arxiv.org
We consider the problem of matchings under two-sided preferences in the presence of
maximum as well as minimum quota requirements for the agents. This setting, studied as the …
