This is an implementation of an ILP model for computing a graph parameter called readability. The model and parameter are described here: https://arxiv.org/pdf/1612.07113.pdf
The model is implemented in Java using CPLEX library for solving integer linear programs. For installing the library, please refer to here: http://www-01.ibm.com/support/docview.wss?uid=swg21449776
Refer to Main.java to check how to compute the readability of graph.
