An Equitable Solution to the Stable Marriage Problem

Ioannis Giannakopoulos, Panagiotis Karras, Dimitrios Tsoumakos, Katerina Doka, Nectarios Koziris
2015 2015 IEEE 27th International Conference on Tools with Artificial Intelligence (ICTAI)  
Gusfield and Irving introduced the equitable stable marriage problem (ESMP), which calls for finding a stable matching that minimizes the distance between men's and women's sum-of-rankings of their spouses  ...  The problem was formulated in 1962 by Gale and Shapley, who showed that any instance can be solved in polynomial time, and has attracted interest due to its application to any two-sided market.  ...  We eschew an exhaustive search over stable matchings, and instead build on the Gale-Shapley algorithm in a manner that treats both sides equitably and still achieves stable solutions.  ...

Fair, Fast and Frugal Large-Scale Matchmaking for VM Placement [chapter]

Nikolaos Korasidis, Ioannis Giannakopoulos, Katerina Doka, Dimitrios Tsoumakos, Nectarios Koziris
2017 Lecture Notes in Computer Science  
To that end, VM placement is expressed as an Equitable Stable Matching Problem (ESMP), where each party's policy is translated to a preference list.  ...  A practical approximation for this NP-hard problem, modified accordingly to ensure efficiency and scalability, is applied to provide equitable matchings within a reasonable time frame.  ...  In the equitable methodology we propose, an approximation algorithm was utilized in order to find a stable and fair matching between the VMs and the available VM slots, so as to honor the policies dictated  ...

The Dichotomous Affiliate Stable Matching Problem: Approval-Based Matching with Applicant-Employer Relations [article]

Marina Knittel, Samuel Dooley, John P. Dickerson
2022 arXiv   pre-print
While the stable marriage problem and its variants model a vast range of matching markets, they fail to capture complex agent relationships, such as the affiliation of applicants and employers in an interview  ...  To address this, we introduce the Dichotomous Affiliate Stable Matching (DASM) Problem, where agents' preferences indicate dichotomous acceptance or rejection of another agent in the marketplace, both  ...  Approximately stable matchings with general giotis Karras.

An algebraic model for fast corner detection

A Willis, Yunfeng Sui
2009 2009 IEEE 12th International Conference on Computer Vision  
The key benefits to this approach are: (1) performance (in space and time); since no image pyramid (space) and no edge-linking (time) is required and (2) compactness; the estimated model includes the corner  ...  must lie close to one of the two intersecting lines, an important aspect to stable corner detection.  ...  We propose a modified version of the repeatability rate for which our detector performs well, especially for structural scenes, where relatively stable and accurate matches have been observed.  ...

safe-control-gym: a Unified Benchmark Suite for Safe Learning-based Control and Reinforcement Learning [article]

Zhaocong Yuan, Adam W. Hall, Siqi Zhou, Lukas Brunke, Melissa Greeff, Jacopo Panerati, Angela P. Schoellig
2022 arXiv   pre-print
However, to adequately gauge the progress and applicability of new results, we need the tools to equitably compare the approaches proposed by the controls and reinforcement learning communities.  ...  In recent years, both reinforcement learning and learning-based control -- as well as the study of their safety, which is crucial for deployment in real-world robots -- have gained significant traction  ...  Control barrier functions (CBF) are safety filters for continuous-time nonlinear control-affine systems using quadratic programming (QP) with a constraint on the CBF's time derivative with respect to the  ...

Colouring random graphs

Colin McDiarmid
1984 Annals of Operations Research  
This amounts to a quadratic expected running time.  ...  In linear time, we can distinguish between two cases. The first is that there is a K 4 subgraph, in which case we apply the quadratic-time 4-colouring algorithm for planar graphs.  ...  Given non-negative integers a and b, we say that an (a, b)-colouring of a graph G is a partition of the vertex-set into a cliques and b stable sets.  ...

Anchored k-medoids: a novel adaptation of k-medoids further refined to measure long-term instability in the exposure to crime

Monsuru Adepeju, Samuel Langton, Jon Bannister
2021 Journal of Computational Social Science  
We find that both methods highlight instability in the exposure to crime over time, but the consistency and contribution of cluster solutions determined by ak-medoids provide insight overlooked by k-medoids  ...  This has important implications for the theories said to explain longitudinal crime concentrations, and the law enforcement agencies seeking to offer an effective and equitable service to the public.  ...  The images or other third party material in this article are included in the article's Creative Commons licence, unless indicated otherwise in a credit line to the material.  ...
