Optimal In-place Sorting of Vectors and Records
Abstract. We study the problem of determining the complexity of optimal comparison-based in-place sorting when the key length, k, is not a constant. We present the first algorithm...

Exact Learning of Discretized Geometric Concepts
We first present an algorithm that uses membership and equivalence queries to exactly identify a discretized geometric concept defined by the union of m axis-parallel boxes in d-...

Recovering Fluid-type Motions Using Navier-Stokes Potential Flow
The classical optical flow assumes that a feature point maintains constant brightness across the frames. For fluidtype motions such as smoke or clouds, the constant brightness ass...

A Randomized Complexity-theoretic Model of Bio-inspired Mobile Epidemics via Close Contact
In this paper we present a randomized complexity theoretic model for those epidemics propagated via short-distance close contact. We prove that the contact-based epidemics problems...

FRR: a proportional and worst-case fair round robin scheduler
In this paper, we propose an O(1) complexity round robin scheduler, called Fair Round Robin (FRR), that provides good fairness and delay properties. Unlike existing O(1) complexit...
