Greetings.
I would still like to know if there is any way to see the actual
time tags
of the wmes while debugging and to know exactly how the conflict
resolution strategy works in detail.
You can get the time tag for a fact by calling getTime() on the
jess.Fact object.
The built-in depth and breadth strategies work the same way, just in
opposite senses. Remember that the conflict resolution strategy is
comparing activations: a tuple containing a rule and a list of facts
that activate it. They first compare salience; for rules of equal
salience, they then compare the most recent time stamp of all the
facts in each token.
If those are also equal, what happens next has varied in different
versions of Jess. In Jess 7, they then compare the sum of all the
time stamps for all the facts in each token. If those are equal, the
order is arbitrary.
You can implement your own strategies in Java; the manual now
contains a reasonable description of how to do this, and there are
some better examples in the Wiki (www.jessrules.com/jesswiki ).
