Parameterized Complexity of Directed Steiner Tree on Sparse Graphs

Mark Jones, Daniel Lokshtanov, M. S. Ramanujan +2

We study the parameterized complexity of the directed variant of the classical {\sc Steiner Tree} problem on various classes of directed sparse graphs. While the parameterized comp…

Kernels for (connected) Dominating Set on graphs with Excluded Topological subgraphs

Fedor V. Fomin, Daniel Lokshtanov, Saket Saurabh +1

We give the first linear kernels for the (Connected) Dominating Set problems on H-topological minor free graphs. We prove the existence of polynomial time algorithms that, for a gi…

SeeSite: Efficiently Finding Co-occurring Splice Sites and Exon Splicing Enhancers

Christine Lo, Boyko Kakaradov, Daniel Lokshtanov +1

The problem of identifying splice sites consists of two sub-problems: finding their boundaries, and characterizing their sequence markers. Other splicing elements---including, enha…

Planar F-Deletion: Approximation, Kernelization and Optimal FPT Algorithms

Fedor Fomin, Daniel Lokshtanov, Neeldhara Misra +1

Let F be a finite set of graphs. In the F-Deletion problem, we are given an n-vertex graph G and an integer k as input, and asked whether at most k vertices can be deleted from G s…

Faster Parameterized Algorithms using Linear Programming

Daniel Lokshtanov, N. S. Narayanaswamy, Venkatesh Raman +2

We investigate the parameterized complexity of Vertex Cover parameterized by the difference between the size of the optimal solution and the value of the linear programming (LP) re…
