middle_square, a C code which implements the middle square algorithm for generating random integers. This is a very early method, attributed to von Neumann, which actually is deeply flawed, with short cycles.

asa183, a C code which implements the Wichman-Hill random number generator (RNG).
c_random_test, a C code which uses C's random number generators.
collatz_recursive, a C code which computes and analyzes the Collatz or hailstone or 3n+1 sequence, using a recursive approach;
cycle_brent, a C code which carries out an iterated function evaluation, and seeks to determine the nearest element of a cycle, and the cycle length, using the Brent method.
cycle_floyd, a C code which carries out an iterated function evaluation, and seeks to determine the nearest element of a cycle, and the cycle length, using the Floyd method.
