Yes parameters are not for the mainstream, by any means. The defaults will be sensible for the majority, options are only for mad tweakers !
What will be interested is when we apply analytical rules over the rules and suggest (or enable/disable) various features intelligently, both statically analysing and runtime heuristics eventually (not unlikes databases do) so the options are handy to have, but they will not influence usability in anyway for the majority cases.

I am not a sure if shadowfacts aren't actually helping instead: I am using exists() for a couple of rules and with 3.0.4 With 3.0.4 I actually saw 2 exists rules increase the evaluation time time by 3, so I suspect the shadowfacts-exists hashing has actually countered that somewhat. But it should be interesting to see what happens by trying to tweak it a bit, for example by turning shadow facts off. Although I agree with Peter that - like the jvm itself - the out-of-the-box experience should have a higher priority then the ability to tweak it with lots of parameters. For taseree-which-needs-a-new-name (drools-solver?:), I have a similar idea: the many tweaking options (tabu list size, ...) make it hard to tweak and scale, so I am thinking of some sort of dynamic defaults in the long run. As for specifically for the TravelingTournament problem: I've found out that there's a much smarter way to do define moves, which would also allow me to remove some rules and greatly reduce the amount of moves. I 'll keep in the current (stupid) way, to demonstrate the difference.
