... Remark The rate of convergence in (8) is better than the rate of the usual algorithms based on the calendar time or business time sampling (this was proved at least for some class of diffusions), and is of the same order as the order of tick time sampling schemes, which are special case of stochasti ...

... Each weighing has three possible outcomes - equal, left pan heavier or right pan heavier. Hence with k weighings, there are 3 k possible outcomes and hence we can distinguish between at most 3k different “states”. Hence 2n + 1 ≤ 3k or n ≤ (3k − 1)/2 . Looking at it from an information theoretic view ...

Ars Conjectandi (Latin for The Art of Conjecturing) is a book on combinatorics and mathematical probability written by Jakob Bernoulli and published in 1713, eight years after his death, by his nephew, Niklaus Bernoulli. The seminal work consolidated, apart from many combinatorial topics, many central ideas in probability theory, such as the very first version of the law of large numbers: indeed, it is widely regarded as the founding work of that subject. It also addressed problems that today are classified in the twelvefold way, and added to the subjects; consequently, it has been dubbed an important historical landmark in not only probability but all combinatorics by a plethora of mathematical historians. The importance of this early work had a large impact on both contemporary and later mathematicians; for example, Abraham de Moivre.Bernoulli wrote the text between 1684 and 1689, including the work of mathematicians such as Christiaan Huygens, Gerolamo Cardano, Pierre de Fermat, and Blaise Pascal. He incorporated fundamental combinatorial topics such as his theory of permutations and combinations—the aforementioned problems from the twelvefold way—as well as those more distantly connected to the burgeoning subject: the derivation and properties of the eponymous Bernoulli numbers, for instance. Core topics from probability, such as expected value, were also a significant portion of this important work.
