Understanding and using the code

The code should be straightforward if you start to read from file main.cpp. Necessary comments have been added in the code for easiness of understanding. Descriptions are added at the top of each function in functions.cpp and classes.cpp.

In file main.cpp, the main function starts by reading in input parameters from file tasksCrossGraph.txt. This file comprises six entries: the number of graph collections (p), the index of the first graph, the index of the last graph, the instance name, k, and the method (which can either be CCF or PPCF). For instance, an entry might look like this: "2 1 2 graph_200_0.1 2 PPCF".
