#### Constructing Near Spanning Trees with Few Local Inspections

Constructing a spanning tree of a graph is one of the most basic tasks in graph theory. Motivated by several recent studies of local graph algorithms, we consider the following variant of this problem. Let \$G\$ be a connected bounded-degree graph. Given an edge \$e\$ in \$G\$ we would like ... more >>>

#### Testing Similar Means

We consider the problem of testing a basic property of collections of distributions: having similar means. Namely, the algorithm should accept collections of distributions in which all distributions have means that do not differ by more than some given parameter, and should reject collections that are relatively far from having ... more >>>

#### Approximating and Testing \$k\$-Histogram Distributions in Sub-linear time

Revisions: 1

A discrete distribution \$p\$, over \$[n]\$, is a \$k\$-histogram if its probability distribution function can be
represented as a piece-wise constant function with \$k\$ pieces. Such a function
is
represented by a list of \$k\$ intervals and \$k\$ corresponding values. We consider
the following problem: given a collection of samples ... more >>>

#### Testing Properties of Collections of Distributions

Revisions: 1

We propose a framework for studying property testing of collections of distributions,
where the number of distributions in the collection is a parameter of the problem.
Previous work on property testing of distributions considered
single distributions or pairs of distributions. We suggest two models that differ
in the way the ... more >>>
