WebBy default, boost::adjacency_list uses boost::no_property, which means that neither points nor lines have properties. In Example 31.11, boost::no_property is passed as a fourth parameter to specify no properties for points. The fifth parameter uses boost::property to define a bundled property. WebThe adjacency_listclass can be used to represent both directed and undirected graphs, depending on the argument passed to the Directedtemplate parameter. Selecting directedSor bidirectionalSchoose a directed graph, whereas undirectedSselects the representation for an undirected

WebAdjacency lists are generally preferred for the representation of sparse graphs, while an adjacency matrix is preferred if the graph is dense; that is, the number of edges E is close to the number of vertices squared, V 2, or if one must be able to quickly look up if there is an edge connecting two vertices.
