[pgrouting-dev] GSoC 2020 - Depth First Search and Sequential Vertex Coloring for pgRouting (Week 4 Report)

Hello everyone,

This is my sixth weekly report of coding and the fourth report of the Official Coding Period. (Week 4 Report)

Any feedback, comments, and suggestions are welcome.

Week 4 Report (June 22nd - June 28th)

  • What did I get done this week?
  • Studied the boost function boost::sequential_vertex_coloring and completed the implementation by calling this boost function.
  • Also modified the relevant files for completing the implementation of the Sequential Vertex Coloring algorithm.
  • Details can be found in [1]
  • The merged pull request can be found in [2]
  • What do I plan on doing next week?
  • I plan to complete the documentation of the function and add the docqueries.
  • If time remains, then I will add the basic pgTAP tests.
  • Details of possible sub-tasks can be found in [3]
  • Am I blocked on anything?
  • This isn’t a blocking issue, but I could not figure out how to create a graph with isolated vertices in pgRouting using the insert_edges function present. Creating a graph with isolated vertices may be needed in the future.
