Acceleration of Shortest Path and Constrained Shortest Path Computation [PDF]

, 2005
We study acceleration methods for point-to-point shortest path and constrained shortest path computations in directed graphs, in particular in road and railroad networks. Our acceleration methods are allowed to use a preprocessing of the network data to create auxiliary information which is then used to speed-up shortest path queries.

Physarum can compute shortest paths [PDF]

Journal of Theoretical Biology, 2012
Physarum Polycephalum is a slime mold that is apparently able to solve shortest path problems. A mathematical model has been proposed by biologists to describe the feedback mechanism used by the slime mold to adapt its tubular channels while foraging two food sources s0 and s1.

A Global Path Planning Algorithm Based on Bidirectional SVGA

Journal of Robotics, 2017
For path planning algorithms based on visibility graph, constructing a visibility graph is very time-consuming. To reduce the computing time of visibility graph construction, this paper proposes a novel global path planning algorithm, bidirectional SVGA (
