Recently, hardness results for problems in P were achieved using reasonable complexity- theoretic assumptions such as the Strong Exponential Time Hypothesis. According to these …
Many fundamental NP NP-hard problems can be formulated as integer linear programs (ILPs). A famous algorithm by Lenstra solves ILPs in time that is exponential only in the …

We revisit the complexity of the classical k-Coloring problem parameterized by clique-width. This is a very well-studied problem that becomes highly intractable when the number of …
Powerful results from the theory of integer programming have recently led to substantial advances in parameterized complexity. However, our perception is that, except for Lenstra's …
Structural graph parameters, such as treewidth, pathwidth, and clique-width, are a central topic of study in parameterized complexity. A main aim of research in this area is to …
An enumeration kernel as defined by Creignou et al.(2017)[11] for a parameterized enumeration problem consists of an algorithm that transforms each instance into one whose …
The notion of resolving sets in a graph was introduced by Slater Proceedings of the Sixth Southeastern Conference on Combinatorics, Graph Theory, and Computing, Util. Math …

Parameterized complexity seeks to use input structure to obtain faster algorithms for NP- hard problems. This has been most successful for graphs of low treewidth: Many problems …
Graph Burning asks, given a graph G=(V, E) and an integer k, whether there exists (b 0,⋯, bk- 1)∈ V k such that every vertex in G has distance at most i from some bi. This problem is …
