[gecoder-users] [ANN] Gecode/R 0.8.1

[Andreas Launila]

Gecode/R 0.8.1 has been released.

It adds tuple constraints along with a couple of minor features. It also
fixes the examples that were broken in the previous release and a bug
related to BAB-search.

== Changes: http://gecoder.rubyforge.org/details/changes.html

* [#19435] Fixed a bug causing inconsistencies during BAB-search. The
bug stopped the send+more=money example from working correctly.
* Fixed the "raw_bindings" and "sudoku-set" examples, which were broken
by the 0.8.0 release.
* Integers can now be used to specify singleton lower and upper bounds
when creating set variables.
* Added convenience methods Model#maximize! and Model#minimize! for
optimizing single variables.
* Added tuple constraints for enumerations of integer and boolean variables.
