Abstract

A framework for solving certain multi-dimensional parametric matroid optimization problems in randomized linear time by prune-and-search is presented. The common feature of these problems, which include the multi-parameter minimum spanning tree problem on planar and dense graphs, is that their fixed-parameter versions are solvable by tournament-like algorithms whose structure is represented by a balanced decomposition tree.
