Timetable Writing 11/12/2011 at 12:05 #24855

9 posts 		Question for any timetable writers...

If I want to set a rule along the lines of 'if train A runs, then train B doesn't', or vice versa. How do I write this in to the rules?
Thanks

Online 		One of the trains referenced in the rule must have 'runs only as required XX% of the time' ticked in the timetable, with XX being any value between 1 and 99, otherwise the earliest train of the two will appear every time. See also this Wiki page.

1098 posts 		Thanks Steamer - there was something nagging me that i forgot something

Put it down to automatically clicking 'runs only as required' every time I set the rule up

9 posts 		Thank for that. I thought it was the mutually exclusive rule, but not having one train shown as only running x% of time, which would explain why it hasn't been working so far.
Thanks

5360 posts 		The has been a problem with Mutually exclusive in some sims in that neither train entered but that seems OK in more recent core code.

Clive has done some further work on the core code in that past week or so as well as it was still not quite right.

The explanation I wrote in the WIKI for MutEx is also not quite right either as it appears mutually exclusive is a slightly different function to the rule pairs of [A notif B] plus [B notif A] which does work as expected. I got it a bit mixed up with the XOR key where by entering the list of trains you want A NotIf B rules for will generate the complete matrix of the NotIf rules.

Is it not the case that in some sims on earlier versions of the core code, the rule pairs of [A notif B] plus [B notif A] do not work as expected? Setting those two rules in the latest public release of the Edinburgh sim result in neither train entering.

Yes, something like that, the discussion took some 35, in some cases quite complex, posting and I'm not minded to try and wade through it all again. Suffice to say there maybe problems on some Sims with some rules and the instructions on the Wiki may need tweaked.

It also never did get to the bottom of what did and didn't happen in older versions of the core code; I was more worried about what *should* happen.

Future sims will have a new rule "XXXX and XXXX are alternatives" where the Xs can also be wildcards. This does the right thing without worrying about probabilities or anything else. If you put "1A01 and 1A02 are alternatives" and "1A03 and 1A02 are alternatives", then the simulation will pick one of 1A01, 1A02, and 1A03 at random to run. If you put "1A99-? are alternatives", then it will pick one at random out of all the 1A99-1, 1A99-2, etc.

That sounds good... especially if it were then made possible to do something with percentages to influence the randomness (possibly a later development).
