Bayesian Information Criterion (BIC) is a promising method for detecting the number of clusters. It is often used in model-based clustering in which a decisive first local maximum ...
In this short note we introduce two new sequences defined using the sum of digits in the representation of an integer in a certain base. A connection to Niven numbers is proposed ...

— We study the problem of determining the minimum number of limited range wavelength converters needed to construct strictly, wide-sense, and rearrangeably nonblocking optical cr...
Given an algebraic number field K, such that [K : Q] is constant, we show that the problem of computing the units group O∗ K is in the complexity class SPP. As a consequence, w...
We present a new paradigm for multicasting. Our paradigm combines two ideas: a simple distributed algorithm for automatically numbering network links with a small amount of numbers...
