Benchmarks "We have developed a new package-management tool, called Opium, that improves on current tools in two ways: Opium is complete, in that if there is a solution, Opium is guaranteed to find it, and Opium can optimize a user-provided objective function, which could for example state that smaller packages should be preferred over larger ones. We performed a comparative study of our tool against Debian's apt-get on 600 traces of real-world package installations. We show that Opium runs fast enough to be usable, and that its completeness and optimality guarantees provide concrete benefits to end users."

Member since:

I would argue that OPIUM is much simpler than APT in the way it solves dependencies.

Simpler, but with the same problems.

As I understand it, your success criteria is that the new package is installed and a minimum of other packages are removed. So, if I ask OPIUM to install "abiword" and it removes "gimp" in the process then that is a successful (and optimal) installation as far as the paper is concerned.

To a user, that probably looks more like failure! The real optimal solution is to install abiword without uninstalling anything.
