Center hyperedge (induced by source paper "faster computation of representative families for uniform matroids with applications"):
  Abstract: Let $M = (E, {\cal I})$ be a matroid, and let ${\cal S}$ be a family of subsets of size $p$ of $E$. A subfamily $\widehat{\cal S} \subseteq {\cal S}$ represents ${\cal S}$ if for every pair of sets $X \in {\cal S}$ and $Y \subseteq E \setminus X$ such that $X \cup Y \in {\cal I}$, there is a set $\widehat{X} \in \widehat{\cal S}$ disjoint from $Y$ such that $\widehat{X} \cup Y \in {\cal I}$. In this paper, we present a fast computation of representative families for uniform matroids. We use our computation to develop {\em deterministic} algorithms that solve {\sc $k$-Partial Cover} and {\sc $k$-Internal Out-Branching} in times $O^*(2.619^k)$ and $O^*(6.855^k)$, respectively. We thus significantly improve the best known {\em randomized} algorithm for {\sc $k$-Partial Cover} and {\em deterministic} algorithm for {\sc $k$-Internal Out-Branching}, that run in times $O^*(5.437^k)$ and $O^*(16^{k+o(k)})$, respectively. Finally, we improve the running times of several algorithms that rely on efficient computation of representative families.
