Unbiased Statistics of a Constraint Satisfaction Problem - a Controlled-Bias Generator
: We show that estimating the complexity (mean and distribution) of the instances of a fixed size Constraint Satisfaction Problem (CSP) can be very hard. We deal with the main two ...

Approximation Algorithms for Flexible Job Shop Problems
The Flexible Job Shop problem is a generalization of the classical job shop scheduling problem in which for every operation there is a group of machines that can process it. The p...

On the subset sum problem over finite fields
Abstract. The subset sum problem over finite fields is a well known NPcomplete problem. It arises naturally from decoding generalized Reed-Solomon codes. In this paper, we study th...

Approximation algorithms via contraction decomposition
We prove that the edges of every graph of bounded (Euler) genus can be partitioned into any prescribed number k of pieces such that contracting any piece results in a graph of bou...
