Center node: "efficient computation of minimum area rectilinear convex hull under rotation and generalizations"
  Abstract: Let $P$ be a set of $n$ points in the plane. We compute the value of $\theta\in [0,2\pi)$ for which the rectilinear convex hull of $P$, denoted by $\mathcal{RH}_{\theta}(P)$, has minimum (or maximum) area in optimal $O(n\log n)$ time and $O(n)$ space, improving the previous $O(n^2)$ bound. Let $\mathcal{O}$ be a set of $k$ lines through the origin sorted by slope and let $\alpha_i$ be the aperture angles of the $2k$ sectors defined by every pair of two consecutive lines. Let $\Theta_{i}=\pi-\alpha_i$ and $\Theta=\min\{\Theta_i:i=1,\ldots,2k\}$. We further obtain: (1) Given a set $\mathcal{O}$ such that $\Theta\ge\frac{\pi}{2}$, we provide an algorithm to compute the $\mathcal{O}$-convex hull of $P$ in optimal $O(n\log n)$ time and $O(n)$ space, while if $\Theta<\frac{\pi}{2}$ the complexities are $O(\frac{n}{\Theta}\log n)$ time and $O(\frac{n}{\Theta})$ space. (2) Given a set $\mathcal{O}$ such that $\Theta\ge\frac{\pi}{2}$, we compute and maintain the boundary of the ${\mathcal{O}}_{\theta}$-convex hull of $P$ for $\theta\in [0,2\pi)$ in $O(kn\log n)$ time and $O(kn)$ space, or in $O(k\frac{n}{\Theta}\log n)$ time and $O(k\frac{n}{\Theta})$ space if $\Theta<\frac{\pi}{2}$. (3) Finally, given a set $\mathcal{O}$ such that $\Theta\ge\frac{\pi}{2}$, we compute the ${\mathcal{O}}_{\theta}$-convex hull of $P$ of minimum (or maximum) area over all $\theta\in [0,2\pi)$ in $O(kn\log n)$ time and $O(kn)$ space.
