Exploiting Cycle Structures in Max-SAT
We investigate the role of cycles structures (i.e., subsets of clauses of the form ¯l1 ∨ l2, ¯l1 ∨ l3, ¯l2 ∨ ¯l3) in the quality of the lower bound (LB) of modern MaxSAT ...

Using the Breakout Algorithm to Identify Hard and Unsolvable Subproblems
Abstract. Local search algorithms have been very successful for solving constraint satisfaction problems (CSP). However, a major weakness has been that local search is unable to de...

Uniform Hardness Amplification in NP via Monotone Codes
We consider the problem of amplifying uniform average-case hardness of languages in NP, where hardness is with respect to BPP algorithms. We introduce the notion of monotone error...

Hardness amplification within NP
We study the average-case hardness of the class NP against deterministic polynomial time algorithms. We prove that there exists some constant ? > 0 such that if there is some l...

Sensor Placement for Triangulation-Based Localization
Robots operating in a workspace can localize themselves by querying nodes of a sensor-network deployed in the same workspace. This paper addresses the problem of computing the min...
