[rules-users] Get maximum

[Swindells, Thomas]

You probably want something like this:

Rule "multiplePeople"
        p1 : Person()
        not Person (age > p1.age)
        not OldestPerson()
then
        insert (new OldestPerson(p1))
end

The oldest person is the person for whom there isn't someone older.
If there are multiple oldest people of the same age this will pick one arbitrarily.
You may want insertLogical if your people can be updated/inserted.

Thomas
