Ben: I'm shocked to discover such a "natural" extension of prev_ and next_permutation, and that one year later it still isn't in the standard. I have a commitment to algorithms and to C++. This should definitely make it in a TR, but IMHO it's simple enough and useful enough that it should even definitely be in C++0x if there's still time. I've had success in getting the boost.minmax library into C++0x (http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2006/n1990.htm), I'm proud to say it took all of ten minutes of the committee's time in Mont-Tremblant for the making the decision. I'll see if I can work on your proposal. Get in touch later. -- HB On Nov 11, 2007, at 11:25 AM, Ben Bear wrote:
Hi, all
`gacap' is template library of "Generating All Combinations and Permutations". It's supper of std::next_permutation() and std::prev_permutation().
There's a old discussion: "[boost] [tr2]Add Combination against std::permutation. HELP!" http://lists.boost.org/Archives/boost/2006/09/110176.php
I register a project in sf.net, http://gacap.wiki.sourceforge.net/. Some introductions are here.
I put a .zip file in the vault, vault/Algorithms/gacap-0.0.4.zip. http://boost-consulting.com/vault/
It can also be downloaded from http://sourceforge.net/project/showfiles.php?group_id=209093
The package contains: gacap's header files doc/ example/ test/
doc/gacap.txt and doc/classes.txt are important introductions.
I test it under three compilers, see doc/compile.txt.
It's one year later.
Thanks. _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/ listinfo.cgi/boost
