I?m making some experiences with different combinatorial search problems, namely

problems with the implementation of the cycle constraint. This means a
constraint that prevents sub-tour elimination.
In this way I want to ask if anyone as already implemented this constraint in
Eclipse, and in affirmative case if it can
send me the code.

There's a simple implementation of a circuit and no_subtours constraints in
Eclipse with CHR, you can get the code from CHR Online at

by clicking at the link "Finite domains over arbitrary ground terms...".
