Locating phase transitions in computationally hard problems
We discuss how phase-transitions may be detected in computationally hard problems in the context of anytime algorithms. Treating the computational time, value and utility functions...

Improved Approximation Algorithms for Metric Maximum ATSP and Maximum 3-Cycle Cover Problems
We consider an APX-hard variant (∆-Max-ATSP) and an APX-hard relaxation (Max-3-DCC) of the classical traveling salesman problem. We present a 31 40-approximation algorithm for ...

Gumshoe: Diagnosing Performance Problems in Replicated File-Systems
Replicated file-systems can experience degraded performance that might not be adequately handled by the underlying fault-tolerant protocols. We describe the design and implementa...

An exact algorithm for a vehicle routing problem with time windows and multiple use of vehicles
The vehicle routing problem with multiple use of vehicles is a variant of the classical vehicle routing problem. It arises when each vehicle performs several routes during the wor...
