I'm probably going to be in London sometime between 27th March and 6th June, as our Friends & Family railcard runs out soon so we (my family) will make the most of it. So anytime between them will be best for me!Going Underground wrote:Let me know when re-worked Hakan and note to all....

And here they are, all 10 unique routes:hwolge wrote:128 is the final score (10 different routes - all Epping to T5)...
List and map will be published tomorrow
https://www.dropbox.com/s/26u056nik2ex0 ... 8.xls?dl=0
As you can see, 8 of them involves W&C line and were missed out on last time around...
With such different routes, maybe some type of competitive event would make sense?

Re: Desktop challenge!
I think the numbering of the lists doesn't agree with the numbering of the pictures. Possibly they're in reverse. For example: pictures for route 1 and 2 don't use the Waterloo & City line, but these are routes 9 and 10 in the lists. Another example: route 10 in the list is the only one to continue from London Bridge to Southwark, but this is route 1 in the pictures.hwolge wrote:And here they are, all 10 unique routes:

The Heathrow configuration means these routes are one way only, so you must start at Epping and there's no variation until you get to London Bridge. So, for the challenge, would everyone go together until London Bridge and then it's up to each team to pick its preferred route?

Re: Desktop challenge!
Historically, this was staggered start - challengers depart Epping every twenty minutes on the same route (connecting well with the 20 minutely Woodford via Hainault), and attempt to catch up the team in front without being caught up by the one behind, am I right?

Re: Desktop challenge!
And here is a list of all (in my mind) reasonable starting stations and the maximum count and number of possibilities achievable for a snake. However, in theory, the optimum start station does not necessarily have to be an end station - one can e.g. easily imagine a topology where there are no end stations! Anyway, I'm convinced that in the LU case, the end stations are the only candidates (some of them, like Mill Hill East, could easily have been excluded for obvious reasons).

Re: Desktop challenge!
Looking at the result, I think the definition of the snake is dubious. Should it really be allowed to cross over/under its own path? I really think not!
So the new desktop challenge is to find the longest snakes that do not cross over themselves (according to the official map - crossing over within stations, by foot or rail, does not count as crossing).
Any takers?

Re: Desktop challenge!
Well, seeing as you lose the via Harrow and Ealing Broadway and have to go to Acton if you want to keep that loop in, I'd imagine you immediately lose the Heathrow finish as sensible.
It shouldn't be too hard to get the maximum because we have our eyes on our side now!

Re: Desktop challenge!
That's well spotted. Without giving everything away, I can say that Epping is still start (or finish - since every route not involving Heathrow is reversible). Any snake not using the north-eastern-most part of Central Line is at least 5 stations less (Cockfosters <-> High Barnet).The Orange One wrote:Well, seeing as you lose the via Harrow and Ealing Broadway and have to go to Acton if you want to keep that loop in, I'd imagine you immediately lose the Heathrow finish as sensible.

Re: Desktop challenge!
How precise do we need to be about crossings? Do we just go by the tube map, or by real life? For example, the southern end of the Bakerloo line crosses the Northern line Charing Cross branch at Lambeth North, but the tube map shows them coming together at Charing Cross. I'm sure there are many more such instances.hwolge wrote:Looking at the result, I think the definition of the snake is dubious. Should it really be allowed to cross over/under its own path?

Also, lines often cross very near to, rather than at, stations, meaning an apparently simple line change at a station can actually be a crossing.

Re: Desktop challenge!
I think we should treat every place where two lines cross, but do not interchange at either of the two stations (e.g. Warren Street and Euston) as a crossing, and every interchange as a single blob (e.g. Piccadilly Line from Caledonian Road to King's Cross St Pancras does not cross the Victoria or Northern Lines until it reaches King's Cross St Pancras, where it meets at an idealised single blob).
If so, then I have the following:
Epping Woodford Stratford via Hainault Waterloo Elephant and Castle Stockwell Victoria Mile End Bank Euston (also possibly with a Farringdon diversion) Tottenham Court Road Holborn Leicester Square Charing Cross Piccadilly Circus Gloucester Road/South Kensington Notting Hill Gate Oxford Circus Baker Street Wembley Park Rayners Lane Acton Town Earl's Court Wimbledon
at 117 - someone should check this. Can anyone do better?
