Philip B. Daniel PhD,Joel F. Habener MD33 ms and about 3 ms suffice for an inexact travel time profile that is just 1 % away from the exact result. In particular, time-dependent routing and travel time profiles are now within easy reach of web servers with massive request traffic.

Distributed Time-Dependent Contraction Hierarchiesization of the arguably best current technique – time-dependent contraction hierarchies, we remove these bottlenecks. For example, on a medium size network 64 processes accelerate preprocessing by a factor of 28 to 160 seconds, reduce per process memory consumption by a factor of 10.5 and increase query throughput by a factor of 25.

Fast FPT Algorithms for Computing Rooted Agreement Forests: Theory and Experimentsd trees and trees inferred from protein sequence data. We show that our algorithm is orders of magnitude faster and can handle much larger trees and SPR distances than the best previous methods, . and ..

Experimental Evaluation of Approximation and Heuristic Algorithms for Sorting Railway Carsally improved 2-approximations. Finally, with an average objective value of only 5.4?% above optimal, the best algorithm gets close to the real-world schedules of the IP approach, so we obtain very satisfactory practical schedules extremely quickly.

Alternative Routes in Road Networkshave small stretch, and are locally optimal. We formally define the problem of finding alternative routes with a single via vertex, develop efficient algorithms for it, and evaluate them experimentally. Our algorithms are efficient enough for practical use and compare favorably with previous methods
