Experimental Analysis of Dynamic Algorithms for the Single Source Shortest Path Problem
- ACM Jounal of Experimental Algorithmics
, 1997
"... In this paper we propose the first experimental study of the fully dynamic single source shortest paths problem on directed graphs with positive real edge weights. In particular, we perform an experimental analysis of three different algorithms: Dijkstra's algorithm, and the two output bound ..."

Practical Efficiency of the Linear-Time Algorithm for the Single Source Shortest Path Problem
- Journal of the Operations Research Society of Japan
"... Abstract Thorup's linear-time algorithm for the single source shortest path problem consists of two phases: a construction phase of constructing a data structure suitable for a shortest path search from a given query source S; and a search phase of finding shortest paths from the query source ..."

A Tight Analysis of the (1 + 1)-EA for the Single Source Shortest Path Problem
"... Abstract — We conduct a rigorous analysis of the (1 + 1) evolutionary algorithm for the single source shortest path problem proposed by Scharnow, Tinnefeld and Wegener (Journal of Mathematical Modelling and Algorithms, 2004). We prove a tight bound of Θ(n 2 max{log(n), ℓ}) on the optimization time, ..."
