Hi,
I am looking for information about nary constraints and propagator
modification event in Gecode/J.
Is there any example or tutorial about a propagator using modification
event and propagation condition to make specific filtering?
For example: if I implement a constraint with three variables and I want
to know why propagator requires to be re-executed. How to detect which
kind of event happened on the variables' domain involve in the constraint ?
Thanks :)
