-
List of .h files in the subfolder "inc":
- Selfmath.h: user-defined c++ library header file for two functions
- To run an algorithm for solving an instance:
- Create a C++ project in Visual Studio;
- Compile C++ project with CPLEX in Concert Technology;
- Load Selfmath.h and the .cpp file of the algorithm into the project;
- Copy the instance data from the "data" folder;
- Load the data into the code for the algorithm between lines "//input data starts here" and "//input data ends here";
- Build and run the code;
- Obtain the results from the console window.
