Perform DFS: We can use thepregelfunction in GraphX to perform DFS. Thepregelfunction is a generalization of the Pregel API for graph computations. It allows us to define the initial messages, vertex program, and message propagation rules. // Define the initial messagesvalinitialMsg=""// Defi...

地图数据常常可以用图(Graph)这类数据结构表示,那么在图结构中常用的搜索算法也可以应用到路径规划中。 本文将从图搜索算法的基本流程入手,层层递进地介绍几种图搜索算法。首先是两种针对无权图的基本图搜索算法:深度优先搜索(Depth First Search, DFS)、广度优先搜索(Breadth First Search, BFS)。它们的区别在于open...

Bestimmen Sie anhand von DFS, ob ein ungerichteter Graph zweigeteilt ist. Ein bipartiter Graph (oder Bigraph) ist ein Graph, dessen Scheitelpunkte in zwei disjunkte Mengen geteilt werden können U und V so dass jede Kante einen Knoten in verbindet U zu einem hinein V. Das Folgende ...
