Iterative Algorithm for Finding the Shortest Ways in an Unweighted Undirected Graph
There is a problem of finding the shortest paths between two vertices in an unweighted, undirected graph, which is aggravated by the fact that the available algorithms for finding all paths have a complexity of at least .

Representative dissimilar path queries: accommodating human movement dynamics in road networks
We introduce a representative dissimilar path (RDP) query, a novel type of path query in road networks. The k representative paths (RPs) between a source and a destination locations have k smallest costs for a feature (e.g., length, number of road ...

Finding $k$ Simple Shortest Paths and Cycles [PDF]
The problem of finding multiple simple shortest paths in a weighted directed graph $G=(V,E)$ has many applications, and is considerably more difficult than the corresponding problem when cycles are allowed in the paths. Even for a single source-sink pair,

Shortest Paths Avoiding Forbidden Subpaths [PDF]
In this paper we study a variant of the shortest path problem in graphs: given a weighted graph G and vertices s and t, and given a set X of forbidden paths in G, find a shortest s-t path P such that no path in X is a subpath of P.

Shortest‐path network interdiction
AbstractWe study the problem of interdicting the arcs in a network in order to maximize the shortest s–t path length. “Interdiction” is an attack on an arc that destroys the arc or increases its effective length; there is a limited interdiction budget.
