This repository contains block-fit, block-gen and block-pred, a suite of three programs to work with stochastic blockmodels (both degree-corrected and standard ones). block-fit fits a standard or degree-corrected blockmodel to a given graph, block-gen generates graphs from a fitted model and block-pred calculates the probability of existence for each possible edge in a grpah from a fitted stochastic blockmodel. More details about the usage of each program are to be found in the doc subfolder. Please also read the references [1] [2] [3] [4] if you are interested in how these models work.

Sorry, we do not provide precompiled binaries yet - you have to compile the tools on your own.

• igraph 0.7.1 or later. This is the library that we use to work with graphs.
• CMake to generate the makefiles (or the project file if you are using Visual Studio).

These instructions are for Linux or Mac OS X and assume that igraph is installed in a way that CMake can figure out automatically where it is. (This usually involves using pkg-config; if you run pkg-config --cflags igraph and it works, then it should work with CMake as well):

$ git submodule update --init
$ mkdir build
$ cd build
$ cmake ..
$ make

The first command is required only after you have checked out the source code from GitHub for the first time. The command fetches the source code of the C++ interface of igraph from GitHub and adds it to the source tree.

Have you found a bug in the code? Do you have questions? Let me know. I think you are smart enough to figure out my email address by googling for my name. Or just drop me a message on GitHub.
