Author Signature

This program computes an "author signature" from a text, with the algorithm from http://unix.dsu.edu/~johnsone/comp.html

Demographic Simulator

Assuming an Adam and an Eve 20 years old each, assuming the current US life table, and assuming an "intensive" reproduction rate, with gene selection, simulate the population growth during 80 years and draw the final age pyramid.
