On the computational complexity of Ham-Sandwich cuts, Helly sets, and related problems

TL;DR: The technique of embedding d-Sum into a geometric setting is conceptually much simpler than direct fpt-reductions from purely combinatorial W[1]-hard problems and has great potential to show (parameterized) hardness and (conditional) lower bounds for many other problems.

Feedback Vertex Set Inspired Kernel for Chordal Vertex Deletion

TL;DR: In this article, a polynomial kernel of size O (k12 log 10k) was proposed, which is the smallest known kernel for CVD of size at most 4.

Model Checking Existential Logic on Partially Ordered Sets

TL;DR: This work investigates structural properties of posets yielding conditions for fixed-parameter tractability when the problem is parameterized by the sentence, and proves that model checking existential logic on classes of finite posets of bounded width is fixed- parameter tractable.

Characterizing arithmetic circuit classes by constraint satisfaction problems

TL;DR: The first natural non-circuit characterization of VP, the class of polynomial families efficiently computable by arithmetic circuits, is given.

Deconstructing Intractability: A Case Study for Interval Constrained Coloring

TL;DR: Several positive (fixed-parameter) tractability results are presented and a large spectrum of combinatorial research challenges for Interval Constrained Coloring is identified, based on a thorough analysis of the known NP-hardness proof.
