    A Parametrized Algorithm for Matroid Branch-Width

  • Original language description

    Branch-width is a structural parameter very closely related to tree-width, but branchwidth has an immediate generalization from graphs to matroids. We present an algorithm that, for a given matroid M of bounded branch-width t which is represented over afinite field, finds a branch decomposition of M of width at most 3t in cubic time. Then we show that the branch-width of M is a uniformly fixed-parameter tractable problem. Other applications include recognition of matroid properties definable in the monadic second-order logic for bounded branch-width, or [Oum] a cubic time approximation algorithm for graph rank-width and clique-width.

    Parametrizovaný algoritmus pro branch-width matroidů

  • Czech description

    Branch-width je strukturální parametr blízký známé tree-width, avšak mající okamžité zobecnění na matroidy. Zde uvedeme algoritmus, který pro daný matroid M s omezenou branch-width ta reprezentovaný nad konečným tělesem najde dekompozici šířky nejvýše 3tv kubickém čase. Tak dokážeme, že branch-width je uniformně FPT problém. Další aplikace zahrnují rozpoznávání matroidových vlastností v monadické logice druhého řádu pro omezenou branch-width, nebo [Oum] kubický aproximační algoritmus pro grafovou rank-width a clique-width.
