摘要

The weighted m-D MATCHING and m-SET PACKING problems (m >= 3) are usually solved through approximation algorithms. In this paper, we define the parameterized versions of these problems and study their algorithms. For the weighted m-SET PACKING problem, we develop a parameterized algorithm of running time 0(12.8(mk)n(0(1))), which is based on the recently improved color-coding technology and dynamic programming. By refining the techniques, we also develop a more efficient parameterized algorithm of running time 0(12.8((m-1)k)n(0(1))) for the weighted m-D MATCHING problem, which is a restricted version of the weighted m-SET PACKING problem.
