There is too much iteration when using the traditional Floyd algorithm to calculate the shortest path, that is to say, the computation of traditional Floyd algorithm is too large for an urban road network with a large number of nodes. As for this disadvantage, the Floyd algorithm was improved and optimized further in this study; moreover, the improved Floyd algorithm was used to solve the shortest path problem in car navigation system, and it achieved good results. Two improvements were done: firstly, construct an iterative matrix for solving the shortest path...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
