The Derivation of Distributed Termination Detection Algorithms from Garbage Collection Schemes
It is shown that the terminationdetection problem for distributed computations can be modeled as an instance of the garbage collection problem. Consequently, algorithms for the te...

Concurrent counting is harder than queuing
In both distributed counting and queuing, processors in a distributed system issue operations which are organized into a total order. In counting, each processor receives the rank...

ROMAN DOMINATION: a parameterized perspective
Abstract. We analyze Roman domination from a parameterized perspective. More specifically, we prove that this problem is W[2]-complete for general graphs. However, parameterized al...

On Parameterized Approximability
Abstract. Combining classical approximability questions with parameterized complexity, we introduce a theory of parameterized approximability. The main intention of this theory is ...

Two Dimensional Parameterized Matching
Two equal length strings, or two equal sized two-dimensional texts, parameterize match (p-match) if there is a one-one mapping (relative to the alphabet) of their characters. Two-...
