Example projects

SCIP contains several examples that demonstrate its usage. They are contained in the "examples" directory in the source code distribution.

Branch-and-price

Binpacking	An implementation of the column generation approach for the binpacking problem. It includes a customized reader, Ryan/Foster branching rule, (global) problem data, variable data, and constraint handler.
VRP	A solver for a simple capacity-constrained vehicle routing problem, which is based on pricing tours via a dynamic programming algorithm.

Branch-and-cut

Linear Ordering	An example for implementing a constraint handler.
The TSP example	A short implementations of a constraint handler, two easy combinatorial heuristics, a file reader, etc. which demonstrate the usage of SCIP as a branch-and-cut-framework for solving traveling salesman problem instances.

Callable library

Callable Library Example	An example showing how to setup constraints (esp. nonlinear ones) when using SCIP as callable library.
MIP solver	A minimal implementation for using SCIP included into another source code
Queens	An example showing the use of SCIP as callable library.

Other plugins

Event handler	A small example illustrating the use of an event handler.
Gomory mixed integer cut example	An example about Gomory mixed-integer cuts.
Relaxator example	An example about using custom relaxators.
