Pollard s rho algorithm for logarithms is an algorithm for solving the discrete logarithm problem analogous to Pollard s rho algorithm for solving the Integer factorization problem. The goal is to compute math gamma math such that math alpha gamma beta math , where math beta math belongs to a Group mathematics group math G math generated by math alpha math . The algorithm computes integers math a math , math b math , math A math , and math B math such that math alpha a beta b alpha A beta B math . Assuming, for simplicity, that the underlying group is cyclic of order math n math , we can calculate math gamma math as a solution of the equation math B b gamma a A pmod n math .

Ezechiel de Decker ca. 1603 ca. 1647 was a Dutch surveyor and teacher of mathematics. Tables of logarithms In 1625, De Decker entered a contract with Adriaan Vlacq for the publication of several translations of books by John Napier , Edmund Gunter and Henry Briggs mathematician Henry Briggs . A first book was published in 1626, with several translations done by Vlacq. A second book was made of the logarithms of the first 10000 numbers from Briggs Arithmetica logarithmica published in 1624. The logarithms were shortened to 10 places. In 1627, De Decker s Tweede deel was published and it contained the logarithms of all numbers from 1 to 100000, to 10 places. Only very few copies of this book are known and its publication was apparently stopped or delayed. In 1628, Vlacq s Arithmetica logarithmica was published and contained exactly the tables published in 1627.

The BKM algorithm is a shift and add algorithm for computing elementary function differential algebra elementary function s, first published in 1994 by J.C. Bajard, S. Kla, and J.M. Muller. BKM is based on computing complex logarithm s and exponential function exponential s using a method similar to the algorithm Henry Briggs mathematician Henry Briggs used to compute logarithms. By using a precomputed table of logarithms of negative powers of two, the BKM algorithm computes elementary functions using only integer add, shift, and compare operations. BKM is similar to CORDIC , but uses a table of logarithms rather than a table of arctangents. On each iteration, a choice of coefficient is made from a set of nine complex numbers, 1, 0, 1, i, i, 1 i, 1 i, 1 i, 1 i, rather than only 1 or 1 as used by CORDIC. BKM provides a simpler method of computing some elementary functions, and unlike CORDIC, BKM needs no result scaling factor. The convergence rate of BKM is approximately one bit per iteration, like CORDIC, but BKM requires more precomputed table elements for the same precision because the table stores logarithms of complex operands. As with other algorithms in the shift and add class, BKM is particularly well suited to hardware implementation. The relative performance of software BKM implementation in comparison to other methods such as polynomial or rational function rational approximations will depend on the availability of fast multi bit shifts i.e, a barrel shifter or hardware floating point arithmetic.

jesuit Alphonse Antonio de Sarasa was a Jesuit mathematician who contributed to the understanding of logarithm s, particularly as area s under a hyperbola . Alphonse de Sarasa was born in 1618, in Nieuwpoort Belgium Nieuwpoort in Flanders. In 1632 he was admitted as a novice in Ghent . It was there that he worked alongside Gregoire de Saint Vincent whose ideas he developed, exploited, and promulgated. According to Sommervogel 1896 , Alphonse de Sarasa also held academic positions in Antwerp and Brussels. In 1649 Alphonse de Sarasa published Solutio problematis a R.P. Marino Mersenne Minimo propositi . This book was in response to Marin Mersenne s pamphlet Reflexiones Physico mathematicae which reviewed Saint Vincent s Opus Geometricum and posed this challenge Given three arbitrary magnitudes, rational or irrational, and given the logarithms of the two, to find the logarithm of the third geometrically. R.P. Burn 2001 explains that the term logarithm was used differently in the seventeenth century. Logarithms were any arithmetic progression which corresponded to a geometric progression . Burn says, in reviewing de Sarasa s popularization of de Saint Vincent, and concurring with Moritz Cantor , that the relationship between logarithms and the hyperbola was found by Saint Vincent in all but name . Burn quotes de Sarasa on this point the foundation of the teaching embracing logarithms are contained in Saint Vincent s Opus Geometricum , part 4 of Book 6, de Hyperbola .

In mathematics , specifically in abstract algebra and its applications, discrete logarithms are group mathematics group theoretic analogues of ordinary logarithm s. In particular, an ordinary logarithm log sub a sub b is a solution of the equation a sup x sup b over the Real Numbers real or complex numbers . Similarly, if g and h are elements of a Finite set finite cyclic group G then a solution x of the equation g sup x sup h is called a discrete logarithm to the base g of h in the group G . Example Discrete logarithms are perhaps simplest to understand in the group Multiplicative group of integers modulo n Z sub p sub sup × sup . This is the set 1, , p &minus 1 of congruence class es under multiplication modular arithmetic modulo the prime number prime p . If we want to find the k th exponentiation power of one of the numbers in this group, we can do so by finding its k th power as an integer and then finding the remainder after division by p . This process is called discrete exponentiation . For example, consider Z sub 17 sub sup × sup .
