 I looked into this because I've wondered about which types of search
 can be improved by classifying structures into "easy to search" vs.
 "hard to search", and using different algorithms as appropriate
 rather than only using an algorithm which works for the hard case.
 However, you don't make it easy for people to try out your software:
   - that URL does not have a download link, which is
       http://people.cs.kuleuven.be/~jan.ramon/fog/readme.html
     I found it by reading one of the PDFs
   - the readme says there is a tests/ subdirectory, but there isn't
   - the code uses "ushort" and "malloc.h" which aren't
 portable.
      I also had to force "CC=g++" in the Makefile in order to
      compile biconn.c (it's a C++ program with a ".c" extension)
   - While I have a copy of the NCI data set, and found the -db=
      option to change the default location for it, I didn't try
      to reverse engineer the format. It's neither SMILES nor SDF.
 In what I can read it doesn't appear to handle what PyMCS handled,
 which is the ability to generate the MCS from a group of compounds.
 I know that other tools, such as GGA's free Indigo toolkit, have
 code to solve this problem. My search for PyMCS is mostly emotional.
 I wrote that code, and I spent about 6 weeks developing it. It was
 the first non-trivial cheminformatics algorithm I wrote and it was
 the basis for some of Bioreason's technology.
 And sadly, no progress on tracking down that code.
