This project is an implementation of Modularity and community structure in networks by M. E. J. Newman in C.
the code was part of an academic project, and the format was as requested.
The output is the communities detected by the algorithm.
In the project, there is an implementation of the optimization suggested in the article as well.
The results was top in class as well as the running time of the code because of the data structure used in the implementation.
