Graph Drawings with One Bend and Few Slopes
We consider drawings of graphs in the plane in which edges are represented by polygonal paths with at most one bend and the number of different slopes used by all segments of thes...

Tree Compression Using String Grammars
We study the compressed representation of a ranked tree by a straight-line program (SLP) for its preorder traversal string, and compare it with the previously studied representatio...

Faster Information Gathering in Ad-Hoc Radio Tree Networks
We study information gathering in ad-hoc radio networks. Initially, each node of the network has a piece of information called a rumor, and the overall objective is to gather all t...

Generating Random Spanning Trees via Fast Matrix Multiplication
We consider the problem of sampling a uniformly random spanning tree of a graph. This is a classic algorithmic problem for which several exact and approximate algorithms are known....

Compressing Bounded Degree Graphs
Recently, Aravind, Sandeep, and Sivadasan (IPEC 2014) showed that for any finite set of connected graphs H, the problem H-Free Edge Deletion admits a polynomial kernelization on ...

A Faster FPT Algorithm and a Smaller Kernel for Block Graph Vertex Deletion
A graph G is called a block graph if each maximal 2-connected component of G is a clique. In this paper we study the Block Graph Vertex Deletion from the perspective of fixed para...
