MB-DPOP: A New Memory-Bounded Algorithm for Distributed Optimization
In distributed combinatorial optimization problems, dynamic programming algorithms like DPOP ([Petcu and Faltings, 2005]) require only a linear number of messages, thus generating...

Reachability on prefix-recognizable graphs
We prove that on prefix-recognizable graphs reachability is complete for deterministic exponential time matching the complexity of alternating reachability. Key words: Reachabilit...

Reducing the Complexity of ILP Formulations for Synthesis
Integer Linear Programming ILP is commonly used in high level and system level synthesis. It is an NP-Complete problem in general cases. There exists some tools that give an o...
