 # Predictive Breakthroughs
 
+This respository contains code to reproduce the results of the predictive breakthroughs manuscript.  In addition, it includes code that can be used independently for cocitation network (CCN) computation and MCL/R-MCL (Regularized Markov Clustering Algorithm).  The R-MCL code algorithm has been tested on networks with more than 25 million nodes and 1 billion edges.
