Our approximation algorithms deliver a (1-∈......ter than known exact algorithms.

The ...... use of fast unweighted matroid intersection algorithms as a black box for designing algorithms. To be precise......we can find an exact solution via solving W unweighted matroid intersections problems, where W is the lar...
