Type: FreewareCRYP is a pseudo-infinite key data encryption system. A very fast and secure method of encrypting data files. Includes all source files for C, C# and Pascal versions of the program.

The algorithm for the Data Encryption Standard (DES) runs too slow on most computers, but simpler methods have not provided secure encryption. CRYP solves this problem by being both fast and secure. DES, though normally considered a very secure form of encryption, has a very complicated algorithm and runs very slow when implemented on a computer. CRYP attempts to be even more secure than DES by using a larger and more random key, and at the same time is reasonably fast.

This is a program for Windows that investigates Goldbach's Conjecture. Goldbach's Conjecture in Euler's form is:

Every even integer 2n >= 4 is the sum of two primes.But for large n there appears to be many decompositions guaranteed.

This program computes terms for The On-Line Encyclopedia of Integer Sequences maintained by N. J. A. Sloane.

See: http://www.research.att.com/~njas/sequences/The sequence generates is:

A135733 1,6,34,64,76,94,166,199,244,244,316,346,496,496,556,556,556,706,706,

Goldbach's conjecture is equivalent to the case when n = 1, a(1) = 1, but for large n there appears to be many decompositions guaranteed. This sequence relies on a heuristic calculation and there is no proof that it is correct.

The General Problem: There is an ordered set of n objects arranged in a circle with object i (1 <= i <= n) in position i. All n objects are selected and removed in a certain order and placed in a new circle with the new position number k beings the order of selection. Object f is selected first. After each selection, m minus 1 of the remaining objects following the one removed are skipped and the next object is then selected. We are interested in the nature of the permutation generated by this process, its fixed elements, and in particular the original position L of the last object selected. Note that m and f can be as low as 1 and can be larger than n.All Turbo Pascal source files are included in the DOS versions.

Juggler Sequence defined in Dr. Clifford A. Pickover's book "Computers and the Imagination." This book has scores of educational and recreational experiments that can be done on a personal computer.At the end of Appendix C in this book you will find:

". . . An award of 50 dollars is offered by the publisher for a printout of the largest Juggler number computed by readers. The award will be given on or about September, 1993, and the sequence will also be published in the Juggernaut. Currently, the largest juggler number computed is a 45,391-digit giant for the starting number 30817. It was computed by Harry J. Smith using his own software package to perform multiple precision integer arithmetic. His package is written in the object-oriented programming language Turbo Pascal 5.5 by Borland International, Inc. His juggler package is a subset of his super-precision calculator software which computes transcendental functions to thousands of decimal places. Write him to obtain the software: Harry J. Smith, 19628 Via Monte Drive, Saratoga, CA 95070. . . ."

Juggler Sequence also defined in Nov 1990 issue of Algorithm in PERSONAL PROGRAMS by Clifford A. Pickover.

Left-Tru is a UBASIC DOS program to compute, sort, and output to a file all left-truncatable primes. There are 4260 of them.A left-truncatable prime is a prime number (without the digit zero) that when you remove any of its left most decimal digit, it still represents a prime number (or no number at all if you remove all of the digits). 5167 is a left-truncatable because 5167, 167, 67, and 7 are all prime.

Perfect is a MS Windows program to compute a perfect number from q, the exponent in a Mersenne prime M(q) = 2^q - 1. When q = 859433 the 517430-digit number is computed and stored on disk in about 5 minutes on a 33 MHz i486 machine.A number is called perfect if it is equal to the sum of its divisors.

Six is perfect: 6 = 1 + 2 + 3.

28 is perfect: 28 = 1 + 2 + 4 + 7 + 14.M(n) = 2^n - 1 is called a Mersenne number.

If M(q) = is prime then it is called a Mersenne prime and q will be prime also.

If q makes a Mersenne prime then P(q) = 2^(q-1) * (2^q - 1) is a Perfect number.All Borland C++ source files are included.

The RPNM series of Calculators is a group of calculator programs that were produced by Harry Smith of Saratoga CA. These calculators are unusual in that they not only provide very extended precision arithmetic (numbers with several thousand digits), but they also permit the user to define the precision for the calculator (up to the limit of your particular system's memory). The ability to set the calculator's precision is desirable to control the speed of the calculations.The calculators also utilize Reverse Polish Notation (RPN), thus the name of the series is RPNMx, for RPN Multiple precision; and x is used to distinguish between the different individual calculators of the series. There are currently three different calculators in the RPNMx series:

In August 1995, the calculation of pi up to 4,294,960,000 decimal digits was succeeded by using a supercomputer at the University of Tokyo. The program was written by D.Takahashi and he collaborated with Dr. Y.Kanada at the computer center, the University of Tokyo. This record should be the current world record. ( Details is shown in the windows help. ) This record-breaking program was ported to personal computer environment such as Windows NT and Windows 95. In order to calculate 33.55 million digits, it takes within 3 days with Pentium 90MHz, 40MB main memory and 340MB available storage. The software is free and the circulation of program is also free!The current record is 1,241,100,000,000 Decimal Digits by Yasumasa Kanada & 9 man team in 2002/09
