Start solution heuristic: Concurrent model clones using shared data structures

The example in this section shows how to use the concept of cloned models sharing data structures introduced in Section Shared data structures for cloned models for the implementation of a start solution heuristic for the classical jobshop scheduling problem. The generation of the start solutions involves concurrent solving of several instances of a subproblem that uses the same input data as the master model and needs to communicate back the detailed results.
