Combination and maximum sum problem...
Suppose I have 7 symbols, A-B-C-D-E-F-G for each combination of TWO symbols, I assign a value to it (e.g. A-B = 10, A-C = 13, B-C = 16) If I would like to find the combination of THREE symbols which has maximum sum of it's sub-combinatioin's value (e.g. A-B-C = A-B + A-C + B-C is larger than other THREE symbols c... 15 Nov 2009 00:18

Lindelof summation?
Hi. I saw this: http://en.wikipedia.org/wiki/Divergent_series#Lindel.C3.B6f_summation But it seems dubious: try it with the divergent Mercator series for log (3), it doesn't converge. What's really going on here? There seems to be an error in the Wikipedia. Also, I saw this: http://en.wikipedia.org/wiki/... 15 Nov 2009 14:30
