Valuated Matroids
- A new Look at the Greedy Algorithm
Abstract.
In this note we study a variant of the greedy algorithm
for weight
functions defined on the system of m-subsets of a given set
E and
characterize completely those classes of weight functions for which this
algorithm works. Well known examples come from matroid theory, new ones
come from valuation theory.
