  2. Longest alternating subsequence - Wikipedia

    en.wikipedia.org/wiki/Longest_Alternating...

    The longest alternating subsequence problem has also been studied in the setting of online algorithms, in which the elements of are presented in an online fashion, and a decision maker needs to decide whether to include or exclude each element at the time it is first presented, without any knowledge of the elements that will be presented in the future, and without the possibility of recalling ...

  3. Dirichlet's test - Wikipedia

    en.wikipedia.org/wiki/Dirichlet's_test

    A particular case of Dirichlet's test is the more commonly used alternating series test for the case [2] [5] = | = | Another corollary is that ∑ n = 1 ∞ a n sin ⁡ n {\textstyle \sum _{n=1}^{\infty }a_{n}\sin n} converges whenever ( a n ) {\displaystyle (a_{n})} is a decreasing sequence that tends to zero.

  5. Linear congruential generator - Wikipedia

    Even in this best case, the low three bits of X alternate between two values and thus only contribute one bit to the state. X is always odd (the lowest-order bit never changes), and only one of the next two bits ever changes. If a ≡ +3, X alternates ±1↔±3, while if a ≡ −3, X alternates ±1↔∓3 (all modulo 8).

  6. Absolutely and completely monotonic functions and sequences

    en.wikipedia.org/wiki/Absolutely_and_completely...

    The notions of completely and absolutely monotone function/sequence play an important role in several areas of mathematics. For example, in classical analysis they occur in the proof of the positivity of integrals involving Bessel functions or the positivity of Cesàro means of certain Jacobi series. [ 6 ]

  7. Longest common subsequence - Wikipedia

    en.wikipedia.org/wiki/Longest_common_subsequence

    This table is used to store the LCS sequence for each step of the calculation. The second column and second row have been filled in with ε, because when an empty sequence is compared with a non-empty sequence, the longest common subsequence is always an empty sequence. LCS(R 1, C 1) is determined by comparing the first elements in each sequence.

  8. Erdős–Szekeres theorem - Wikipedia

    en.wikipedia.org/wiki/Erdős–Szekeres_theorem

    Given a sequence of length (r − 1)(s − 1) + 1, label each number n i in the sequence with the pair (a i, b i), where a i is the length of the longest monotonically increasing subsequence ending with n i and b i is the length of the longest monotonically decreasing subsequence ending with n i.

  9. Dirichlet eta function - Wikipedia

    en.wikipedia.org/wiki/Dirichlet_eta_function

    Color representation of the Dirichlet eta function. It is generated as a Matplotlib plot using a version of the Domain coloring method. [1]In mathematics, in the area of analytic number theory, the Dirichlet eta function is defined by the following Dirichlet series, which converges for any complex number having real part > 0: = = = + +.
