Discrete geometry on colored point sets in the plane—a survey

M Kano, J Urrutia - Graphs and Combinatorics, 2021 - Springer
Discrete geometry on colored point sets in the plane has a long history, but this research
area has been extensively developed in the last 2 decades. In 2003, a short survey entitled …

[HTML][HTML] Matching points with disks with a common intersection

C Huemer, P Pérez-Lantero, C Seara, RI Silveira - Discrete Mathematics, 2019 - Elsevier
We consider matchings with diametral disks between two sets of points R and B. More
precisely, for each pair of matched points p∈ R and q∈ B, we consider the disk through p …

On maximum-sum matchings of points

S Bereg, OP Chacón-Rivera, D Flores-Peñaloza… - Journal of Global …, 2023 - Springer
Abstract Huemer et al.(Discrete Mathematics, 2019) proved that for any two point sets R and
B with| R|=| B|, the perfect matching that matches points of R with points of B, and maximizes …

Transition operations over plane trees

TL Nichols, A Pilz, CD Tóth, AN Zehmakan - Discrete Mathematics, 2020 - Elsevier
The operation of transforming one spanning tree into another by replacing an edge has
been considered widely, both for general and planar straight-line graphs. For the latter …

[HTML][HTML] Flip distance to some plane configurations

A Biniaz, A Maheshwari, M Smid - Computational Geometry, 2019 - Elsevier
We study an old geometric optimization problem in the plane. Given a perfect matching M on
a set of n points in the plane, we can transform it to a non-crossing perfect matching by a …

Flips in odd matchings

O Aichholzer, A Brötzner, D Perz, P Schnider - arxiv preprint arxiv …, 2024 - arxiv.org
Let $\mathcal {P} $ be a set of $ n= 2m+ 1$ points in the plane in general position. We define
the graph $ GM_\mathcal {P} $ whose vertex set is the set of all plane matchings on …

Disjoint compatibility graph of non-crossing matchings of points in convex position

O Aichholzer, A Asinowski, T Miltzow - arxiv preprint arxiv:1403.5546, 2014 - arxiv.org
Let $ X_ {2k} $ be a set of $2 k $ labeled points in convex position in the plane. We consider
geometric non-intersecting straight-line perfect matchings of $ X_ {2k} $. Two such …

Quasi-parallel segments and characterization of unique bichromatic matchings

A Asinowski, T Miltzow, G Rote - arxiv preprint arxiv:1302.4400, 2013 - arxiv.org
Given n red and n blue points in general position in the plane, it is well-known that there is a
perfect matching formed by non-crossing line segments. We characterize the bichromatic …

[HTML][HTML] Linear transformation distance for bichromatic matchings

O Aichholzer, L Barba, T Hackl, A Pilz… - Computational …, 2018 - Elsevier
Abstract Let P= B∪ R be a set of 2n points in general position in the plane, where B is a set
of n blue points and R a set of n red points. A BR-matching is a plane geometric perfect …

Packing plane perfect matchings into a point set

A Biniaz, P Bose, A Maheshwari… - Discrete Mathematics & …, 2015 - dmtcs.episciences.org
Given a set P of n points in the plane, where n is even, we consider the following question:
How many plane perfect matchings can be packed into P? For points in general position we …
