This code is part of my bachelor thesis [1].

1. Get Stuttgart, Baden-Württemberg and Deutschland graph from here
2. Create data folder and place graph files in there
3. Compile with sh build.sh -r
4. Run with ./build/olsp (Default: runs predefined benchmarks for all graphs without independent sets)
5. (To define custom benchmarks edit src/main.cpp file (see example function). Available graph functions can be found in src/graph.h)
