Cutting a tree with Subgraph Complementation is hard, except for some small trees

For a graph property Π , Subgraph Complementation to Π is the problem to find whether there is a subset S of vertices of the input graph G such that modifying G by complementing the subgraph induced

Subgraph Complementation

A subgraph complement of the graph G is a graph obtained from G by complementing all the edges in one of its induced subgraphs. We study the following algorithmic question: for a given graph G and

Incompressibility of H-free edge modification problems: Towards a dichotomy

A set of nine 5-vertex graphs whose incompressibility would give a complete classification of the kernelization complexity of H-free Edge Editing for every graph $H$ with at least 5 vertices that is neither complete nor empty.

Polynomial Kernels for Paw-free Edge Modification Problems

This work answers both questions affirmatively by presenting, respectively, $O (k)$-vertex and $O(k^4)$ -vertex kernels for them as part of an ongoing program that aims at understanding compressibility of H-free edge modification problems.

A Polynomial Kernel for Paw-Free Editing

The question of compressibility for one of the last two unresolved graphs H on $4$ vertices is positively answered and the first polynomial kernel for paw-free editing with $O(k^{6})$vertices is given.

Which Problems Have Strongly Exponential Complexity

A generalized reduction that is based on an algorithm that represents an arbitrary k-CNF formula as a disjunction of 2?nk-C NF formulas that are sparse, that is, each disjunct has O(n) clauses, and shows that Circuit-SAT is SERF-complete for all NP-search problems.

Edge-Deletion Problems

This paper shows that the edge-deletion problem is NP-complete for the following properties: (1) without cycles of specified length l, or of any length $ \leqq l$, (2) connected and degree-constrained, (3) outerplanar, (4) transitive digraph, (5) line-invertible, (6) bipartite, (7)transitively orientable.

Dichotomy Results on the Hardness of H-free Edge Modification Problems

It is proved that these NP-complete problems cannot be solved in parameterized subexponential time, i.e., in time $2^{o(k)}\cd...

On Switching to H‐Free Graphs

The problem of deciding if, for a fixed graph H, a given graph is switching equivalent to an H-free graph is studied, showing that for H isomorphic to a claw, the problem is polynomial, and giving infinitely many graphs H such that the problems are NP-complete.
