Talk:Rearrangement inequality

The uses section should be partitioned into information for the greedy algorith, intermediate, and olympiad sections. A few examples will add worlds of clarity for readers.--MCrawford 01:24, 20 June 2006 (EDT)

I think that "similarly sorted" has not been defined very well here. For example, the sequences {1,1,1,1,1,1}; {1,2,3,4,5,6} are similarly sorted, but the fifth 1 in the first sequence is greater than or equal to five other terms, whereas the 5 in the second sequence is only greater than or equal to four other terms. At the moment, I can't think of a good definition for "similarly sorted" that doesn't take up a great deal of space. Perhaps we should create a page for similarly vs. opposite sorting, and link to that? After all, it's kind of easy to tell what it means, and an external link would not, I think, be a severe inconvenience. Or could someone else write a more precise (but still concise) definition?
