no. of path in GridIn a Diagram shown in figure, Not that the Grid path from F to G is missing. Last edited by jacks (20130930 03:30:44) #4 20130930 03:36:39
Re: no. of path in GridHi; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #6 20130930 04:03:13
Re: no. of path in GridFor ones that have missing intersections and are small the vertex counting method will work fine. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #8 20130930 04:54:51
Re: no. of path in GridThere is an analytical answer for these type but the counting method is easier to understand. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #10 20130930 07:45:20

Re: no. of path in GridIt is just adding up all the paths in the lattice around the missing intersection. In mathematics, you don't understand things. You just get used to them.

Re: no. of path in GridHi The limit operator is just an excuse for doing something you know you can't. “It's the subject that nobody knows anything about that we can all talk about!” ― Richard Feynman “Taking a new step, uttering a new word, is what people fear most.” ― Fyodor Dostoyevsky, Crime and Punishment #15 20131001 05:17:51
Re: no. of path in GridIt's the number of paths from A to F times the number of paths from G to B.

Re: no. of path in Grid
This is the reason. These are all the paths that become unavailable when we remove the line.

Re: no. of path in GridEven better then.

Re: no. of path in GridThere is another more general way. That maybe can answer for many missing intersections. In mathematics, you don't understand things. You just get used to them.
