Approximation Algorithms for Asymmetric TSP by Decomposing Directed Regular Multigraphs
A directed multigraph is said to be d-regular if the indegree and outdegree of every vertex is exactly d. By Hall’s theorem one can represent such a multigraph as a combination ...

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 â...

Implementation and Evaluation of a Parallel-External Algorithm for Cycle Structure Computation on a PC-Cluster
Abstract: We report on our experiences with the implementation of a parallel algorithm to compute the cycle structure of a permutation given as an oracle. As a sub-problem, the cyc...

Large Spurious Cycle in Global Static Analyses and Its Algorithmic Mitigation
We present a simple algorithmic extension of the classical call-strings approach to mitigate substantial performance degradation caused by spurious interprocedural cycles. Spuriou...

Exploiting Idle Cycles for Algorithm Level Re-Computing
Although algorithm level re-computing techniques can trade-off the detection capability of Concurrent Error Detection (CED) vs. time overhead, it results in 100% time overhead whe...
