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...
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....
We consider three related online problems: Online Convex Optimization, Convex Body Chasing, and Lazy Convex Body Chasing. In Online Convex Optimization the input is an online seque...

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 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...

Abstract. We study a subclass of tree-to-word transducers: linear treeto-word transducers, that cannot use several copies of the input. We aim to study the equivalence problem on t...
Abstract. Finding minimal separating sequences for all pairs of inequivalent states in a finite state machine is a classic problem in automata theory. Sets of minimal separating s...
Two of the most celebrated results that effectively exploit visual representation to give logical characterization and decidable modelchecking include visibly pushdown automata (V...
Capacitated automata (CAs) have been recently introduced in [8] as a variant of finite-state automata in which each transition is associated with a (possibly infinite) capacity. ...
