A Bio-Inspired Method for the Constrained Shortest Path Problem [PDF]
The Scientific World Journal, 2014 The constrained shortest path (CSP) problem has been widely used in transportation optimization, crew scheduling, network routing and so on. It is an open issue since it is a NP-hard problem.

Neutrosophic Shortest Path Problem [PDF]
Neutrosophic Sets and Systems, 2018 Neutrosophic set theory provides a new tool to handle the uncertainties in shortest path problem (SPP). This paper introduces the SPP from a source node to a destination node on a neutrosophic graph in which a positive neutrosophic number is assigned to ...

On Solving the Quadratic Shortest Path Problem [PDF]
INFORMS Journal on Computing, 2017 The quadratic shortest path problem is the problem of finding a path in a directed graph such that the sum of interaction costs over all pairs of arcs on the path is minimized.

A lower bound for the shortest path problem [PDF]
Proceedings 15th Annual IEEE Conference on Computational Complexity, 2002 AbstractWe show that the shortest path problem cannot be solved in o(logn) time on an unbounded fan-in PRAM without bit operations using poly(n) processors, even when the bit-lengths of the weights on the edges are restricted to be of size O(log3n). This shows that the matrix-based repeated squaring algorithm for the shortest path problem is optimal in

On the Quadratic Shortest Path Problem [PDF]
The Sea, 2015 Finding the shortest path in a directed graph is one of the most important combinatorial optimization problems, having applications in a wide range of fields. In its basic version, however, the problem fails to represent situations in which the value of the objective function is determined not only by the choice of each single arc, but also by the ...

Shortest Path Problems on a Polyhedral Surface [PDF]
Algorithmica, 2009 We develop algorithms to compute edge sequences, Voronoi diagrams, shortest path maps, the Fréchet distance, and the diameter for a polyhedral surface. Distances on the surface are measured either by the length of a Euclidean shortest path or by link distance. Our main result is a linear-factor speedup for computing all shortest path edge sequences on

Random assignment and shortest path problems [PDF]
Discrete Mathematics & Theoretical Computer Science, 2006 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 C. Nair, B. Prabhakar and M. Sharma in 2003.

Variations on the Stochastic Shortest Path Problem [PDF]
International Conference on Verification, Model Checking and Abstract Interpretation, 2014 In this invited contribution, we revisit the stochastic shortest path problem, and show how recent results allow one to improve over the classical solutions: we present algorithms to synthesize strategies with multiple guarantees on the distribution of ...
