Developer's Description

Lothar Collatz was born 6 July 1910 in Amsberg, Westphalia. During hispost-doctoral studies at at the age of 27, Collatz developed what isnow known as the Collatz Conjecture.Simply stated, the Collatz Conjecture is as follows:Given the function f, defined as: n2 if n 0 (mod 2)f(n) = 3n + 1 if n 1 (mod 2) for any positive starting integer n, repeated iterations of thisfunction will always lead to the cycle { 4, 2, 1 }. In other words,repeated iterations of some starting number will always be eventuallydecreasing and that there are no other cycles in the sequence besides{ 4, 2, 1 }.The Reverse function, f', is defined as the sequence moving backwardfrom an ending integer through to some initial starting integer thatwould eventually arrive at the number entered through a series ofiterations. It is defined as follows: n2 if n 0, 1, 2, 3, 5 (mod 6)f'(n) = (n - 1)3 if n 4 (mod 6) & "Previous" pressed n2 if n 4 (mod 6) & "Multiply" pressedThis application was written by Jeffrey C.
