Graph theory is one of those things in the computer science field that has the stigma of being extremely hard and near impossible to understand. My goal for this post is to introduce you to graph theory and show you one approach to finding the shortest path in a graph using Dijkstra's Al...
PATHS & cycles (Graph theory)ROBUST optimizationPOLYNOMIALSALGORITHMSNUMBER theoryThis paper is concerned with a biobjective routing problem, called the shortest path with shortest detour problem, in which the length of a route is minimized as one criterion and, as second, the maximal length of a ...
Indeed, all the shortest path algorithms currently available31,32 and generally implemented in graph theory software (Table 2) seek to minimize the value of the path between two nodes calculated as the sum of the edge weights. The reason being that a minimization problem converges, while ...
In graph theory, the shortest path problem is the problem of finding a path between two vertices (or nodes) in a graph such that the sum of the weights of its constituent edges is minimized.The problem of finding the shortest path between two intersections on a road map may be modeled ...

Single source shortest path (SSSP) is a fundamental problem in graph theory. However, the existing SSSP implementations on field-programmable gate arrays (FPGAs) are incapable of processing large graphs by storing the graph and results in internal memories. In this brief, we propose a parallel ...

These kernels are computable in polynomial time, retain expressivity and are still positive definite. In experiments on classification of graph models of proteins, our shortest-path kernels show significantly higher classification accuracy than walk-based kernels. 展开 ...
