PageRank Algorithm December 9‚ 2012 Abstract This paper dicsusses the PageRank algorithm. We carefully go through each step of the algorithm and explain each procedure. We also explain the mathematical setup of the algorithm‚ including all computations that are used in the PageRank algorithm. Some of the topics that we touch on include the following‚ but not limited to‚ are: linear algebra‚ node analysis‚ matrix theory‚ and numerical methods. But primarily this paper concerns itself with

Normally‚ web requests are sent over regular HTTP‚ where a client’s request and the server’s response are both sent as plain text. Public key encryption is a type of cryptographic system where each party has both a private and a public key‚ which are mathematically linked to each other. The public key is used for encrypting plaintext to “ciphertext” (essentially‚ gibberish)‚ while the private key

account for the purported unambiguity of the Sanskrit language. A Computational Algorithm based on Empirical Analysis‚ that Composes Sanskrit Poetry Rama N.‚ Meenakshi Lakshmanan (Submitted on 7 Mar 2010) Poetry-writing in Sanskrit is riddled with problems for even those who know the language well. This is so because the rules that govern Sanskrit prosody are numerous and stringent. We propose a computational algorithm that converts prose given as E-text into poetry in accordance with the metrical

A singular value decomposition (SVD) Centering and rescaling of the data and various rescalings of the results Variance estimation by the delta method. Other names for SVD are “Eckart-Young decomposition” after Eckart and Young (1936)‚ who introduced the technique in psychometrics‚ and “basic structure” (Horst‚ 1963). The rescalings and centering‚ including their rationale‚ are well explained in Benzécri (1969)‚ Nishisato (1980)

and OPT algorithms (other than looking backward versus forward in time) is that the FIFO algorithm uses the time when a page was brought into memory‚ whereas the OPT algorithm uses the time when a page is to be used. If we use the recent past as an approximation of the near future‚ then we can replace the page that has not been used for the longest period of time (see Fig. 9.14). Figure 9.14: LRU page-replacement algorithm. This approach is the least-recently-used (LRU) algorithm. The result
