Hello Douglas, thanks for your prompt reply and the comments.
Few minor changes I believe it is ready to go into Boost 1.35.0.
In fact, I have made several improvements to the algorithm since last December, and I'll update the sources I submitted then (which, again, will need re-naming and re-formatting etc.) and build in the changes that you request. Whether you think they're minor or not, this will take some time. I'll post a message when the new version is in the vault. Cheers, Michael P.S.: In the Boost vault where I put my code, there's also a code for solving the matching problem. It's been posted there even earlier. Have you already looked at this code? I think for the general public, a code for the matching problem is still more interesting than for the ESPPRC.
