The Impossibility of Simultaneous Time and I/O Optimality for The Planar Maxima and Convex Hull Problems
Peyman Afshani, Gerth Stølting Brodal, Nodari Sitchinava
We prove that no deterministic output-sensitive algorithm for the planar convex hull and maxima problems can obtain both optimal time and I/O complexity, where the optimality is de…

Partition-based Simple Heaps
Gerth Stølting Brodal, John Iacono, Casper Moldrup Rysgaard +1
We introduce a new family of priority-queue data structures: partition-based simple heaps. The structures consist of doubly-linked lists; order is enforced among data i…
