Table of Contents
The CBC distribution includes a number of .cpp sample files. Users are encouraged to use them as starting points for their own CBC projects. The files can be found in the COIN/Cbc/Samples/ directory. For the latest information on compiling and running these samples, please see the file COIN/Cbc/Samples/INSTALL. Most of them can be built by
make DRIVER=name
which produces an executable testit. Below is a list of some of the most useful sample files with a short description for each file.
Table 8.1. Basic Samples
| Source file | Description |
|---|---|
| minimum.cpp | This is a CBC "Hello, world" program. It reads a problem in MPS file format, and solves the problem using simple branch-and-bound. |
| sample2.cpp | This is designed to be a file that a user could modify to get a useful driver program for his or her project. In particular, it demonstrates the use of CGL's preprocess functionality. It uses CbcBranchUser.cpp, CbcCompareUser.cpp and CbcHeuristicUser.cpp with corresponding *.hpp files. |
Table 8.2. Advanced Samples
| Source file | Description |
|---|---|
| crew.cpp | This sample shows the use of advanced branching and a use of priorities. It uses CbcCompareUser.cpp with corresponding *.hpp files. |
| longthin.cpp | This sample shows the advanced use of a solver. It also has coding for a greedy heuristic. The solver is given in CbcSolver2.hpp and CbcSolver2.cpp. The heuristic is given in CbcHeuristicGreedy.hpp and CbcHeuristicGreedy.cpp. It uses CbcBranchUser.cpp and CbcCompareUser.cpp with corresponding *.hpp files. |
| qmip.cpp | This solves a quadratic MIP. It is to show advanced use of a solver. The solver is given in ClpQuadInterface.hpp and ClpQuadInterface.cpp. It uses CbcBranchUser.cpp and CbcCompareUser.cpp with corresponding *.hpp files. |
| sos.cpp | This artificially creates a Special Ordered Set problem. |
| lotsize.cpp | This artificially creates a Lot Sizing problem. |
