The final method described here and used for experiments is called Analytic Pro-
gramming (AP), which has been compared to GP with very good results (see, for
example, [26, 15, 27]) or visit the online univeristy website [http://www.fai.utb.cz/
people/zelinka/ap].
The basic principles of AP were developed in 2001 and first published in [24, 25].
AP is also based on the set of functions, operators and terminals, which are usually
constants or independent variables alike, for example:
1. functions: sin, tan, tanh, And, Or
2. operators: +, -, *, /, dt,
3. terminals: 2.73, 3.14, t,
All these mathematical objects create a set, from which AP tries to synthesize an
appropriate solution. Because of the variability of the content of this set, it is called a
