On year ago, we (the mancoosi team) published a comparison study regarding the state of the art of dependency solving in debian. As few noticed, the data presented had few glitches that I promised to fix. So we've repeated our tests using exactly the same data we used one year ago, but now using the latest available versions of all package managers as available in debian unstable.
Recently, all relevant packages needed to run mpm (the mancoosi package manager) landed in debian (thanks ralf and zack !). Now it should be a tad easier to run mpm and to play with it. The code of mpm is available on the mancoosi svn repository (user/pass : mancoosi/mancoosi) . To run it, you also need to install python-apt.
These are all cudf solvers you can use as mpm backends.
After a bit of work, today I decided to start using mpm, the mancoosi package manager, to upgrade my laptop. My first use of it on a production system - until now I run all my experiments in throw-away virtual machines - and it works !
Not rocket science here. During the last month David Kalnischkies (of APT fame) visited our offices in Paris and together with zack worked out a communication protocol between apt-get and the mancoosi cudf solvers (EDSP). I guess somebody is going to announce all details about this endeavor soon.
Here at mancoosi we have been working for quite a while to promote and advance solver technology for FOSS distributions. We are almost at the end of the project and it is important to make the mancoosi technology relevant for the community. On goal of the project is to provide a prototype that uses part of the results of mancoosi that can based to install/remove/upgrade packages on a user machine. We certainly don't want to create yet another meta installer. This would be very time consuming and certainly going beyond the scope of the project.
