Hi Ben, and Merry Xmas to you too, slightly belatedly (although in my time zone it was still Xmas an hour ago :) Ben, I don't know if your emails are lost, I can see as part of this thread the last messages are dated Dec 24 (11:24am, 10:27am), Dec 23 (8:38pm), Dec 8 (11:19am), Dec 7 (10:17pm, 11:31:am, 5:17am). I haven't responded as fast as usual(?) because of the holidays. I've looked at the test code you wrote, not for very long I'm afraid. I'm glad if we both find no errors in the code. Regarding the ordering of the sequences for combination counts, your note was very interesting. I don't know which one is more valuable, the (ordered) sequence of combination counts, or the sequence of counts such that the actual combinations are in lexicographical order. Let's make a decision, soon. One important factor (for me): Is there an implementation of your algorithm (sequence of counts such that the actual combinations are in lexicographical order) as a free function, without state? I.e., with the interface that I give in the proposal? Cheers, -- Hervé Brönnimann hervebronnimann@mac.com On Dec 24, 2007, at 11:23 AM, Ben Bear wrote:
Herve, my test is put in vault/Algorithms/combination_test_btb.cpp. And another address: http://www.bxmy.org/combi/combinatin_test_btb.cpp
I wonder if some of email I sent are lost...
