Objective : 
Find a function, in symbolic form, 

that is the integral of a curve 

presented either as a mathematical 

expression or as a given finite 

sample of points (x_{i},y_{i}) 
Terminal Operands: 
X (the independent variable) 
Terminal Operators 
The binary operators +, *, 

/, and the unary operators 

Sin, Cos, Exp and Log 
Fitness cases 
The given sample of 50 data 

points in the interval [] 
Raw Fitness 
The sum, taken over the 50 fitness 

cases, of the absolute value of the 

difference between the individual 

genetically produced function 

f_{j}(x_{i}) at the domain point x_{i} 

and the value of the numerical 

integral I(x_{i}) 
Standardised Fitness 
Same as raw fitness 
Hits 
The number of fitness cases for 

which the error is less than 0.01 
Wrapper 
Standard productions to generate 

C functions 
Parameters 
M = 500, G = 51
