Major enhancements in ABACUS 3.0 include the new solver interface to Osi, the ability to solve LPs with the Volume
Algorithm and support for state-of-the-art GNU compilers. The documentation system has been changed from cweb to
doxygen and the build process has been simplified. ABACUS 3.0 is released under the Gnu Lesser General Public License
(LGPL). See section 3.1 for details.
We thank the members of Michael Jünger’s group for many stimulating discussions and valuable insights that helped
improve the current release. Special thanks go to Christoph Buchheim, Frauke Liers, Thomas Lange (all University of
Cologne) and Markus Chimani (University of Dortmund).
