7 bridgesWhat is the seven bridges? "The most incomprehensible thing about the universe is that it is comprehensible." Albert Einstein #2 20130702 14:02:39
Re: 7 bridgesHi Amartyanil; 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. #3 20130702 14:08:02
Re: 7 bridgesDidn't know there's an MIF page on it 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #4 20130702 14:11:06
Re: 7 bridgesThere is an MIF page on everything.

Re: 7 bridges
Nope. Atleast sphider doesn't get it. 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #6 20130702 14:16:38
Re: 7 bridgesI did not mean everything in the exact sense there is no page about me there... 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. #7 20130702 14:47:03
Re: 7 bridgesYou can ask him to make one 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #8 20130702 14:47:35
Re: 7 bridgesI did, he won't budge! 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. #9 20130702 14:51:46
Re: 7 bridgesWe do not have a page about NQueens either 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #10 20130702 14:52:33
Re: 7 bridgesThat is right but I have a good post about it. 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. #11 20130702 14:56:48
Re: 7 bridgesLink? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #12 20130702 15:03:43
Re: 7 bridgesSorry, I did a nice post on non attacking rooks which is harder. I got confused. 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. #13 20130702 15:06:00
Re: 7 bridgesI think it is easier than that 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #14 20130702 15:10:52
Re: 7 bridgesIt sure is, I have the definitive work on such problems. 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. #15 20130702 23:27:27
Re: 7 bridgesOK. Would you explain a code? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #16 20130703 02:18:17
Re: 7 bridgesYou mean a program? 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. #17 20130703 02:49:06
Re: 7 bridgesYes. From here: http://en.wikipedia.org/wiki/Eight_queens_puzzle Code:from itertools import permutations n = 8 cols = range(n) for vec in permutations(cols): if (n == len(set(vec[i] + i for i in cols)) == len(set(vec[i]  i for i in cols))): print vec 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: 7 bridgesHi; 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. #19 20130703 03:12:50
Re: 7 bridgesI read somewhere that it filters out the solutions from the Rook problem 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #20 20130703 03:23:58
Re: 7 bridgesThat is correct. Then it only has to check like a bishop. Off course there is a little more to that routine. In mathematics, you don't understand things. You just get used to them.
