The .sssp.bellmanFord algorithm computes the shortest path distances from a single source vertex to all other vertices in the graph using the Bellman-Ford algorithm. Neptune Analytics implements the algorithm such that: Positive edge weights must be provided using the edgeWeightProperty field Negative...
We first present our algorithm and give a formal proof of its correctness. Then, we give an analytical evaluation of the proposed solution.doi:10.1016/j.akcej.2020.01.002Muteb AlshammariAbdelmounaam RezguiAKCE International Journal of Graphs and Combinatorics...
The .sssp.deltaStepping.path algorithm uses the deltaStepping algorithm to find the shortest path along with the shortest path distances from a source node to a target node in the graph. If there are multiple shortest paths between the source node and the target node, only one will be return...
SELECT * FROM findShortestPath( ON (SELECT 1) PARTITION BY 1 GRAPH_TABLE (‘<graph table name>’) RESULT_TABLE(‘<result table name>’) SOURCE(‘<source point id>’) ); The processing algorithm that uses the cogroup feature and the sample SQL is as follows. Assume initially that the...

We show how to solve a single source shortest path problem on a planar network in time O(n 3/2 log n). The algorithm works for arbitrary edge weights (positive and negative) and is based on the planar separator theorem. More generally, the algorithm works in time O(n a+b log n +...

We present a simple parallel algorithm for the single-source shortest path problem in planar digraphs with nonnegative real edge weights. The algorithm runs on the EREW PRAM model of parallel computation in O((n2ε+n1−ε) log n) time, performing O(n1+ε log ...
