Re: no. of path in Grid
I like your first method. It is easily programmable. 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 #27 20131014 19:33:45
Re: no. of path in GridYou mean labeling the vertices with the sums? 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. #28 20131014 19:36:12
Re: no. of path in GridYep. DP is really nice.

Re: no. of path in GridBut there is a much nicer way that is probably quicker too! 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. #30 20131014 19:50:53
Re: no. of path in GridWhich is?

Re: no. of path in GridI am being called away so I will show the method as soon as I get back. 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. #32 20131014 20:08:54
Re: no. of path in GridOkay, no hurry. And if they threaten you, just ask yourself WWHD?

Re: no. of path in GridWWHD? Why Would Hay Decompose? Now run MatrixPower[A, 8][[1]] the last entry means from 1 to 24, 38 ways. In mathematics, you don't understand things.

Re: no. of path in GridIt takes much londer if you have a larger grid. I'd say DP is better here.

Re: no. of path in GridThe matrix can be filled by a program as the "Dice" guy does. Also it is a lot easier for a computer to do. In mathematics, you don't understand things.

Re: no. of path in GridI'm not sure if getting the 8th piwer if a huge matrix is fast.

Re: no. of path in GridHohohohohohohoo! That is a good one! I just talked to Mathematica and he said it sure is. Also there are ways to just get one element of that matrix! 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.

Re: no. of path in GridWhat if you had a grid 100 by 100. You would need to get th 100th power of a 10201 by 10201 matrix!

Re: no. of path in GridThen what?

Re: no. of path in GridThere is an interesting little idea in Computer math that might help. In mathematics, you don't understand things. You just get used to them.

Re: no. of path in GridMatrix moves is the one. 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. #44 20131017 06:47:30
Re: no. of path in GridI'd say that's the same thing I said.

Re: no. of path in GridI meant to say that I think me were thinking about the sane thing in posts #42 and #43.

Re: no. of path in GridThen that is proof of ESP. 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.
