Is it possible to generate multiple custom vertices using the Bundle Properties from Boost Graph Library?

Question

I'm trying to generate an application that solves the bipartite assignment problem via the auction algorithm with the boost graph library. I found it possible to characterize vertices and edges with multiple properties using the boundle properties. But since the auction algorithm envolve two types of entities, persons and items, I was wondering if there was the possibility of generating more than one characterization of vertices in order to suppor this distinction.

Thanks for the help.

Answer 1

This question is overly broad, but let me try to provide some helpful pointers.

But since the auction algorithm [i]nvolve two types of entities, persons and items, I was wondering if there was the possibility of generating more than one characterization of vertices in order to suppor[t] this distinction.

It think "But" can be dropped.

Answering the question, it seems obvious that you can include a type discriminator, like:

 struct VertexProperties {
      int multiple;
      std::string characterizing, properties;
      // for auction algorithm:
      bool isPersonEntity;
      // or e.g.
      enum {Person, Item} entityType;
 };

Here's several answers that show such classifications in action using BGL:

• using a manual type discriminator like just mentioned: Boost graph Library using Bundled properties
• using variant
  1. Graph with two types of nodes
  2. showing how to use filtered_graph to "view" only part of the vertices at a time: boost::adjancency_list with polymorphic vertices and edges
  3. parsing Cars/Planes from XML Storing a nested XML structure in form of BGL graph using BOOST library
• using shared pointers (allowing polymorphic property types) Using boost graph library with a custom class for vertices
• alternatives using dynamic property maps How to use boost::graph dijkstra's algorithm if vertex properties are pointers?
