This booklet constitutes the complaints of the eleventh overseas laptop technology Symposium in Russia, CSR 2016, held in St. Petersburg, Russia, in June 2016.

The 28 complete papers provided during this quantity have been rigorously reviewed and chosen from seventy one submissions. additionally the publication comprises four invited lectures. The scope of the proposed issues is kind of wide and covers quite a lot of parts resembling: contain, yet are usually not constrained to: algorithms and knowledge buildings; combinatorial optimization; constraint fixing; computational complexity; cryptography; combinatorics in computing device technological know-how; formal languages and automata; computational types and ideas; algorithms for concurrent and dispensed platforms, networks; evidence thought and purposes of common sense to machine technology; version checking; computerized reasoning; and deductive methods.

Periodic Tales: A Cultural History of the Elements, from Arsenic to Zinc

just like the alphabet, the calendar, or the zodiac, the periodic desk of the chemical components has an enduring position in our mind's eye. yet other than the handful of universal ones (iron, carbon, copper, gold), the weather themselves stay wrapped in secret. we don't comprehend what so much of them appear like, how they exist in nature, how they obtained their names, or of what use they're to us. Unlocking their spectacular secrets and techniques and colourful pasts, Periodic stories is a passionate trip via mines and artists’ studios, to factories and cathedrals, into the woods and to the ocean to find the real tales of those attention-grabbing yet mysterious development blocks of the universe.

The Lady Anatomist: The Life and Work of Anna Morandi Manzolini

Anna Morandi Manzolini (1714-74), a lady artist and scientist, surmounted meager origins and restricted formal schooling to turn into probably the most acclaimed anatomical sculptors of the Enlightenment. the girl Anatomist tells the tale of her arresting lifestyles and occasions, in gentle of the intertwined histories of technology, gender, and paintings that advanced her upward thrust to repute within the eighteenth century.

Since this cycle goes through non-trivial group elements, Ec (g, h) has a nontrivial state for all c, so is non-trivial for all c, and Engel(g, h) does not hold. 4 Proof of Theorem 1 The Grigorchuk group G0 is contracting, with contraction coefficient η = 1/2. Therefore, the conditions of validity of Algorithm 1 are not satisfied by the Grigorchuk group, so that it is not guaranteed that the algorithm will succeed, on a given element h ∈ G0 , to prove that h is not Engel. However, nothing forbids us from running the algorithm with the hope that it nevertheless terminates.

We have C0 (And2 ) = s0 (And2 ) = 1 and s1 (And2 ) = 2. To construct the examples for larger s0 (f ) values, we use the following fact (it is easy to show, and a similar lemma was proved in [3]): Fact 1. Let f and g be Boolean functions. By composing them with OR to f ∨ g we get C0 (f ∨ g) = C0 (f ) + C0 (g), s0 (f ∨ g) = s0 (f ) + s0 (g), (34) (35) s1 (f ∨ g) = max(s1 (f ), s1 (g)). (36) Suppose we need a function with k = s0 (f ). Assume k is even. Then by Fact 1 for g = k−1 2 i=1 k 2 i=1 Sort4 we have C0 (g) = 3 2 k.
