Effective bounding techniques for solving unate and binate covering problems
Covering problems arise in many areas of electronic design automation such as logic minimization and technology mapping. An exact solution can critically impact both size and perf...

Online Primal-Dual Algorithms for Covering and Packing Problems
We study a wide range of online covering and packing optimization problems. In an online covering problem a linear cost function is known in advance, but the linear constraints th...

On Approximating an Implicit Cover Problem in Biology
Abstract. In an implicit combinatorial optimization problem, the constraints are not enumerated explicitly but rather stated implicitly through equations, other constraints or auxi...

A Local 2-Approximation Algorithm for the Vertex Cover Problem
We present a distributed 2-approximation algorithm for the minimum vertex cover problem. The algorithm is deterministic, and it runs in (∆ + 1)2 synchronous communication rounds,...
