The (M, W)-controller, originally studied by Afek, Awerbuch, Plotkin, and Saks, is a basic ted tool that provides an abstraction for managing the consumption of a global resource ...
Based on the framework of parameterized complexity theory, we derive tight lower bounds on the computational complexity for a number of well-known NP-hard problems. We start by pr...

Gupta (SODA'01) considered the Steiner Point Removal (SPR) problem on trees. Given an edge-weighted tree T and a subset S of vertices called terminals in the tree, find an edg...
