This example contains a branch-and-price approach for the binpacking problem which is realized with the framework SCIP. Therefore, the following plugins are implemented:

In the following we introduce the problem, explain the use of the reader plugin and pricer plugin. Finally, we introduce the Ryan/Foster branching rule and briefly discuss how that specific branching rule is realized within the framework SCIP.

  1. Problem description
  2. Parsing the input format and creating the problem
  3. Main problem data
  4. Pricing new variables
  5. Ryan/Foster branching
