BubbleSearch: A simple heuristic for improving priority-based greedy algorithms
We introduce BubbleSearch, a general approach for extending priority-based greedy heuristics. Following the framework recently developed by Borodin et al., we consider priority al...

Optimal 2-constraint satisfaction via sum-product algorithms
We show that for a given set of m pairwise constraints over n variables, a variable assignment that satisfies maximally many m constraints (MAX-2-CSP) can be found in O(nm dn/3) t...

On the relationship between squared pairings and plain pairings
In this paper, we investigate the relationship between the squared Weil/Tate pairing and the plain Weil/Tate pairing. Along these lines, we first show that the squared pairing for ...

Strongly secure ramp secret sharing schemes for general access structures
Ramp secret sharing (SS) schemes can be classified into strong ramp SS schemes and weak ramp SS schemes. The strong ramp SS schemes do not leak out any part of a secret explicitly...

A fixed-parameter tractability result for multicommodity demand flow in trees
We study an NP-hard (and MaxSNP-hard) problem in trees--Multicommodity Demand Flow--dealing with demand flows between pairs of nodes and trying to maximize the value of the routed...

On the hardness of approximating Max-Satisfy
Max-Satisfy is the problem of finding an assignment that satisfies the maximum number of equations in a system of linear equations over Q. We prove that unless NPBPP Max-Satisfy c...

An adjustable linear time parallel algorithm for maximum weight bipartite matching
We present a parallel algorithm for finding a maximum weight matching in general bipartite graphs with an adjustable time complexity of O(n ) using O(nmax(2,4+)) processing
