Linear Programs with Conjunctive Database Queries

Florent Capelli, Nicolas Crosetti, Joachim Niehren +1

In this paper, we study the problem of optimizing a linear program whose variables are the answers to a conjunctive query. For this we propose the language LP(CQ) for specifying li…

A lower bound on the probability that a binomial random variable is exceeding its mean

Christos Pelekis, Jan Ramon

We provide a lower bound on the probability that a binomial random variable is exceeding its mean. Our proof employs estimates on the mean absolute deviation and the tail condition…

Hoeffding's inequality for sums of weakly dependent random variables

Christos Pelekis, Jan Ramon

We provide a systematic approach to deal with the following problem. Let be, possibly dependent, -valued random variables. What is a sharp upper bound on th…
