Non Uniform Random Walks [PDF]
Given $\epsilon _i ∈ [0,1)$ for each $1 < i < n$, a particle performs the following random walk on $\{1,2,...,n\:\}$par If the particle is at $n$, it chooses a point uniformly at random (u.a.r.) from $\{1,...,n-1\}$.

Tail Bounds for the Wiener Index of Random Trees [PDF]
Upper and lower bounds for the tail probabilities of the Wiener index of random binary search trees are given. For upper bounds the moment generating function of the vector of Wiener index and internal path length is estimated.

HyperLogLog: the analysis of a near-optimal cardinality estimation algorithm [PDF]
This extended abstract describes and analyses a near-optimal probabilistic algorithm, HYPERLOGLOG, dedicated to estimating the number of \emphdistinct elements (the cardinality) of very large data ensembles.

Asymptotics of Riordan arrays [PDF]
The machinery of Riordan arrays has been used recently by several authors. We show how meromorphic singularity analysis can be used to provide uniform bivariate asymptotic expansions, in the central regime, for a generalization of these arrays.

Multivariate Topology Simplification [PDF]
Topological simplification of scalar and vector fields is well-established as an effective method for analysing and visualising complex data sets. For multivariate (alternatively, multi-field) data, topological analysis requires simultaneous advances ...

The volume and time comparison principle and transition probability estimates for random walks [PDF]
This paper presents necessary and sufficient conditions for on- and off-diagonal transition probability estimates for random walks on weighted graphs. On the integer lattice and on may fractal type graphs both the volume of a ball and the mean exit time ...

On expected number of maximal points in polytopes [PDF]
We answer an old question: what are possible growth rates of the expected number of vector-maximal points in a uniform sample from a polytope.

(Non)Existence of Pleated Folds: How Paper Folds Between Creases [PDF]
We prove that the pleated hyperbolic paraboloid, a familiar origami model known since 1927, in fact cannot be folded with the standard crease pattern in the standard mathematical model of zero-thickness paper.

Rapid preconditioning of data for accelerating convex hull algorithms [PDF]
Given a dataset of two-dimensional points in the plane with integer coordinates, the method proposed reduces a set of n points down to a set of s points s ≤ n, such that the convex hull on the set of s points is the same as the convex hull of the ...
