Colored packing of sets

1987
Abstract Let H be a family of t-sets on {l,2, …, k }. A family of k-sets on v elements is called a (v, k, ϰ)-packing if for all F ∈ there is a copy of ϰ, ϰ F such that the t-sets of F corresponding to H F are covered only by F.

Packing Densities of Colored and Non-Colored Patterns

GS4 Student Scholars Symposium 2015, 2015
Pattern packing concerns finding an optimal permutation that contains the maximum number of occurrences of a given pattern and computing the corresponding packing density. In many instances such an optimal permutation can be characterized directly and the number of occurrences of the pattern in interest may be enumerated explicitly. In more complicated

Algebraic and Combinatorial Algorithms for S-Packing Coloring

ACM Communications in Computer Algebra
S -packing coloring is a generalization of proper coloring of graphs, introduced more than a decade ago. In this paper, we present algebraic and combinatorial algorithms for the problem of S -packing coloring of finite undirected and unweighted graphs. We assess the upper bounds for the complexity of our

Note on packing patterns in colored permutations

Online Journal of Analytic Combinatorics, 2016
Packing patterns in permutations concerns finding the permutation with the maximum number of a prescribed pattern. In 2002, Albert, Atkinson, Handley, Holton and Stromquist showed that there always exists a layered permutation containing the maximum number of a layered pattern among all permutations of length n. Consequently the packing density for all

A set packing model for the Partition Coloring Problem

Carpathian Journal of Mathematics
In this paper we propose a set packing model for the Partition Coloring Problem (PCP) a gener alization of the Vertex Coloring Problem (VCP). Given a graph whose vertex set is partitioned in clusters, PCP aims to select one vertex from each cluster such that the chromatic number of the resulted induced subgraph is minimal.

Covering, Coloring, and Packing Hypergraphs

2017
A hypergraph \(\mathcal {H}=(\mathcal V,\mathcal E)\) consists of a (finite) vertex set \(\mathcal V\) and a set of hyper-edges \(\mathcal E\), where each edge \(E\in \mathcal E\) is a subset of \(E\subset \mathcal V\). The vertices will usually be labelled by \(\mathcal V=(v_1,\dots ,v_I)\), the edges by \(\mathcal E=(E_1,\dots ,E_J)\), where \(I,J\in
