In this post, we will see how to resolve Boost Graph Library – Dijkstra’s shortest path fails when the edge weights are large? Question: I have a question regarding the edge weights when using Dijkstra’s algorithm in Boost. The problem ...

Question: I am trying to add edges to a Boost undirected graph using boost::add_edge(…). The graph is defined as: I do not get compile errors. My code works fine, if the vertices are ints (e.g. boost::add_edge(1, 2, g)). However, as ...

Question: I have a an adjacency_list graph with randomly connected nodes using Erdos-Renyi edge generation. The graph uses bundled properties by defining data structures both for the vertices (Graph_Node) and edges (Graph_Edge), which is used to assign the position of ...

Question: I am attempting to call breadth_first_search, starting from vertex 0, and obtain the shortest distance to all other vertices in the graph. How am I calling the function incorrectly? And what container is recommended to store the result? Answer: ...

Question: I created the simplest directed graph possible using boost::graph, and added 2 vertices that are mutually connected via 2 edges. After removing the first vertex, the second vertex still has an out-edge that points to the previously removed vertex. ...
