Talk:Ghost leg

Merge: Amidakuji
I support the merge, Amidakuji and Ghost Leg really are the same thing... both articles have interesting information about the topic; the Amidakuji article is more accessible and easier to read, but it's worth keeping the mathematical analysis found here — although that part deserves a good rewriting to a more concise form. --Patrick Bernier 11:23, 10 February 2007 (UTC)

Diagram text could be clearer
It's not easy to understand step 4 from the diagram. I read it, and my immediate question was "How do you trace your path?". It looks like there are many different possible paths, and there is nothing to stop contestants from choosing the one that's most advantageous to them. I know this is explained in more detail in the main text, but it seems as if the diagram was meant to be self-sufficient, and in that respect I think it falls short. 86.186.34.238 (talk) 00:45, 3 December 2010 (UTC).


 * Imo. it's not the text, but the diagram itself that adds misunderstanding. By marking the route for "C", of all routes, on first glance it makes it look as if there was a rule to always follow to the right, until you hit the rightmost vertical line and then always to the left - and then it doesn't make sense anymore (every route would then end in 2 or 6). Every other route in that diagram would have been clearer. All but route "C" would show unmistakenly that the route is to follow every horizintal line it encounters, no matter if to the right or to the left. So I suggest changing that. 46.142.44.144 (talk) 06:38, 2 January 2016 (UTC)

Song?
Isn't there a song you're supposed to sing while you trace your path? Could some Japanese person shed some light on this? 70.116.13.152 (talk) 04:24, 31 December 2012 (UTC)

Predictability
I removed the sentence "The more lines that are added, the more unpredictable the final outcome is." The outcome is always predictable, in fact it is 100% so. More lines make it more difficult to grasp quickly what the outcome is, but that is irrelevant for prediction. — Preceding unsigned comment added by 188.181.84.236 (talk) 06:18, 21 October 2013 (UTC)

Bubblization
I believe that bubblization identity 1 is only valid if there is either no vertical line to the right of the pattern, or if there is, that it does not contain a leg. Otherwise you'd end up with two legs next to each other, which is undefined.
