How to use the model from Python

#Make sure that cython extension is installed
#> pip install --user cython

# The source code of the add8_175 extension needs to be downloaded first
> curl -s "https://ehw.fit.vutbr.cz/evoapprox8b/master?folder=adders_8&file=source_c/add8_175.c&pyx=bash" | bash

#Finally, the extension can be used in a Python script as follows
> python
import pyximport; pyximport.install()
import add8_175

wce = e = 0
for i in range(0,2**8):
    for j in range(0,2**8):
        diff = abs(add8_175.add(i,j) - (i+j))
        if diff > wce: wce = diff
        e += diff

print('average error magnitude (mae)',e/(2.0**(9)))
print('worst-case error magnitude (wce)',wce)
