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...
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...

One of the most challenging problems in large scale dynamic graphs is the single-source shortest path (SSSP) problem. Traditional solutions (based on Dijkstra's algorithms) to the SSSP problem do not scale to large dynamic graphs with a high change frequency. In this paper, we propose an ...
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 ...
