O(n log n) Filtering Algorithms for Unary Resource Constraint
So far, edge-finding is the only one major filtering algorithm for unary resource constraint with time complexity O(n log n). This paper proposes O(n log n) versions of another t...

Domain Transmutation in Constraint Satisfaction Problems
We study local interchangeability of values in constraint networks based on a new approach where a single value in the domain of a variable can be treated as a combination of &quo...

Convex drawings of graphs with non-convex boundary constraints
: In this paper, we study a new problem of convex drawing of planar graphs with non-convex boundary constraints. It is proved that every triconnected plane graph whose boundary is ...

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...

Maximum Weighted Matching with Interference Constraints
In this paper, we study the problem of utility maximization in multi-hop wireless systems. To study the effect of wireless interference constraints on the utility maximization pro...
