Two-degree-of-freedom manipulator path planning based on zeroing neural network [PDF]
In this paper, the shortest path problem of manipulator path planning is transformed into a linear programming problem, and solved by zeroing neural network (ZNN).

Speed-up Technique in Time-Varying Shortest Path Problems with Arbitrary Waiting Times [PDF]
Network flow problems are considered a vital branch of operations research. These problems are classified into static and time-varying classes. Network flow problems are time-varying in real application, because any flow must take a given amount of time ...

ON ASSOCIATIVE SHORTEST PATH PROBLEMS [PDF]
Summary: We consider a wide class of shortest path problems in acyclic digraphs. In the problems, the length of a path is defined by using an associative binary operation. We derive recursive equations in dynamic programming for the problems, which involve additive, multiplicative, multiplicative-additive, minimum and fractional shortest path problems.

The Capacity Expansion Path Problem in Networks
This paper considers the general capacity expansion path problem (GCEP) for the telecommunication operators. We investigate the polynomial equivalence between the GCEP problem and the constrained shortest path problem (CSP) and present a pseudopolynomial

Reachability and Shortest Paths in the Broadcast CONGEST Model [PDF]
In this paper we study the time complexity of the single-source reachability problem and the single-source shortest path problem for directed unweighted graphs in the Broadcast CONGEST model.

Shortest Reconfiguration of Perfect Matchings via Alternating Cycles [PDF]
Motivated by adjacency in perfect matching polytopes, we study the shortest reconfiguration problem of perfect matchings via alternating cycles. Namely, we want to find a shortest sequence of perfect matchings which transforms one given perfect matching ...

Neutrosophic Shortest Path Problem (NSPP) in a Directed Multigraph [PDF]
One of the important non-linear data structures in Computer Science is graph. Most of the real life network, be it a road transportation network, or airlines network or a communication network etc., cannot be exactly transformed into a graph model, but ...

Rerouting shortest paths in planar graphs [PDF]
A rerouting sequence is a sequence of shortest st-paths such that consecutive paths differ in one vertex. We study the the Shortest Path Rerouting Problem, which asks, given two shortest st-paths P and Q in a graph G, whether a rerouting sequence exists ...

“rsppfp”: An R package for the shortest path problem with forbidden paths
The Shortest Path Problem with Forbidden Paths (SPPFP) is a variant of the original shortest path problem, where the constraints come from a set of forbidden arc sequences that cannot be part of any feasible solution.
