Webboost::adjacency_list is a template that is instantiated with default parameters in Example 31.1. Later, you will see what parameters you can pass. This class is defined in boost. All classes and functions from Boost.Graph are defined in this namespace. To add four points to the graph, the function boost::add_vertex () has to be called four times. 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. mashinesoft.com

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.
