Getting started
===============
Example is compiled in binary 'parity'. Usage options is described by
executing it with command-line argument '-OBusage'. The detailed help can
also be obtained with argument '-OBhelp'.
Objective
=========
Find a program that produces the value of the Boolean even 6-parity given
six independent Boolean inputs.
Terminal set
============
IN0, IN1, IN2, IN3, IN4, and IN5, the inputs of the function.
0 and 1, two Boolean constants.
Function set
============
AND
OR
NAND
NOR
Automatically defined functions
===============================
Two ADFs used, each with two arguments inputs.
Fitness cases
=============
All the $2^6 = 64$ combinations of the six input Booleans.
Fitness
=======
Rate of correct outputs obtained over all the 64 fitness cases.
Stopping criteria
=================
When the evolution reaches the maximum number of generations.
