      -  2011-07:  Version 0.1 released
      -  2013-05:  Version 1.0 released (now also works with QRP)
      -  2014-05:  Version 2.0 released (can perform certificate minimization)
      -  2015-01:  Version LP  released (works with LQ resolution proofs)




      - ResQu is a tool for deriving Herbrand/Skolem functions from Q-resolution and Q-consensus proofs.
      - Input formats:

- QBC (proof formats of Squolem, EBDDRES);
- Proof format of Qube-cert;
- QRP (Proof format of cDepQBF);
- RFAO (local input format as a right-firat-and-or formula just for certificate optimization)

      - Output formats: BLIF (format of ABC synthesis tool), RFAO (same as above)

Installation and Configuration

      - The download folder contains the following materials:

- "README" file explaining current features and usage of ResQu;
- /ResQu/: executables "ResQu_v2" and "ResQu_lp";
- /OtherTools/: some useful tools for complete execution workflow;
- /Examples/: examples of different proofs and certificates;
- "run_ResQu.sh": example of execution ResQu script.
