Tight Multiple Twins in Permutations
نویسندگان
چکیده
Two permutations are similar if they have the same length and relative order. A collection of $$r\geqslant 2$$ disjoint, subsequences a permutation $$\pi $$ forms r-twins in . We study longest guaranteed which tight sense that either each twin alone block or their union does. address question with respect to random permutation.

Twins in words and long common subsequences in permutations
A large family of words must contain two words that are similar. We investigate several problems where the measure of similarity is the length of a common subsequence. We construct a family of n permutations on n letters, such that LCS of any two of them is only cn, improving a construction of Beame, Blais, and Huynh-Ngoc. We relate the problem of constructing many permutations with small LCS t...
متن کاملMultiple cerebral aneurysms in identical twins.
We report the finding of multiple cerebral aneurysms in a pair of identical twins. One twin had subarachnoid hemorrhage and intracerebral hematoma; her sister had subarachnoid hemorrhage and intraventricular bleeding. Angiography in both cases showed multiple cerebral aneurysms. It is appropriate to recommend a cerebral angiographic examination of an asymptomatic twin after the other twin has s...
متن کاملOn the XOR of Multiple Random Permutations
A straightforward way of constructing an n-bit pseudorandom function is to XOR two or more pseudorandom permutations: p1 ⊕ . . .⊕pk. This XOR construction has gained broad attention over the last two decades. In this work, we revisit the security of this well-established construction. We consider the case where the underlying permutations are considered secret, as well as the case where these p...
متن کاملGenesis of Twins and Multiple Pregnancy
A large number of embryological processes must be carried out for the development of a new human being. There are numerous sources of error that can lead to malformations up to stillbirths. However, deviations can also occur within these processes, which lead to the development of two or more children, that is to say, twins or generally multiple births. This article explains how exactly this is...
متن کاملTight security bounds for multiple encryption
Multiple encryption—the practice of composing a blockcipher several times with itself under independent keys—has received considerable attention of late from the standpoint of provable security. Despite these efforts proving definitive security bounds (i.e., with matching attacks) has remained elusive even for the special case of triple encryption. In this paper we close the gap by improving bo...
