Before focusing on graph traversal, we first determine how to represent a graph. In fact, there are mainly two ways to represent a graph, either using adjacency lists or adjacency matrix. An adjacency list is an array of lists. Each list corresponds to a node of the graph and stores the ...

There is an undirected graph with n nodes, numbered from 0 to n - 1. You are given a 2D integer array edges where edges[i] = [ai, bi] denotes that there exists an undirected edge connecting nodes ai and bi. Return the number of pairs of different nodes that are unreachable from ...

some arbitrary node of a graph, sometimes referred to as a ‘search key’[1]), and explores all of the neighbor nodes at the present depth prior to moving on to the nodes at the next depth level.It uses the opposite strategy as depth-first search, which instead explores the highest-...
1.3 Contributions and Outline This paper discusses the mechanical verification of the parallel NDFS algorithm of Laarman et al. [25] using VerCors. To the best of our knowledge, this is the first mechanical verification of a parallel graph (and model checking) algorithm. Section 2 recalls both ...
