Random assignment and shortest path problems [PDF]
We explore a similarity between the $n$ by $n$ random assignment problem and the random shortest path problem on the complete graph on $n+1$ vertices. This similarity is a consequence of the proof of the Parisi formula for the assignment problem given by

Near-shortest and K-shortest simple paths
Summary: We present a new algorithm for enumerating all near-shortest simple (loopless) \(s\)-\(t\) paths in a graph \(G=(V,E)\) with nonnegative edge lengths. Letting \(n=|V|\) and \(m=|E|\), the time per path enumerated is \(O(nS(n,m))\) given a user-selected short-est-path subroutine with complexity \(O(S(n,m))\).

Shortest path poset of Bruhat intervals [PDF]
Let $[u,v]$ be a Bruhat interval and $B(u,v)$ be its corresponding Bruhat graph. The combinatorial and topological structure of the longest $u-v$ paths of $B(u,v)$ has been extensively studied and is well-known.

Most of the previous studies on mobile robot path planning consider the obstacles as polygons. However, the complex shaped obstacles should be considered as curves rather than polygons, since the latter may result in non-optimal paths.

A Novel Method for Solving Multi-objective Shortest Path Problem in Respect of Probability Theory
Transportation process or activity can be considered as a multi-objective problem reasonably. However, it is difficult to obtain an absolute shortest path with optimizing the multiple objectives at the same time by means of Pareto approach. In this paper,

Stochastic Shortest Path Games [PDF]
Summary: We consider dynamic, two-player, zero-sum games where the ``minimizing'' player seeks to drive an underlying finite-state dynamic system to a special terminal state along a least expected cost path. The ``maximizer'' seeks to interfere with the minimizer's progress so as to maximize the expected total cost.

Reconfiguring Shortest Paths in Graphs
AbstractReconfiguring two shortest paths in a graph means modifying one shortest path to the other by changing one vertex at a time so that all the intermediate paths are also shortest paths. This problem has several natural applications, namely: (a) repaving road networks, (b) rerouting data packets in a synchronous multiprocessing setting, (c) the ...

Maritime Transport Network in Korea: Spatial-Temporal Density and Path Planning
The increase in maritime traffic and vessel size has strengthened the need for economical and safe maritime transportation networks. Currently, ship path planning is based on past experience and shortest route usage. However, the increasing complexity of
