make allTo get this to compile with a modern CPP, we had to replace #D with #define.
Run the program this way:
./ovdluhe < textfileThe program stops when it reaches the end of the template buffer by chance or is killed.
./try.sh ; sleep 2 ; ./try.shThe author suggested that one varies the definition of P from 2 through 10. As
it’s a #define it’s easy to set up.
make P=9 clobber altYou do not have to define P but if you do you can replace the value with
whatever you wish, as long as it’s a positive int (or evaluates to a positive
int like the default (A<<AP) does). Too high a value will likely cause the
program to fail and a negative value will cause a compilation error.
./ovdluhe.alt./try.alt.sh
P=5 ./try.alt.shNOTE: if you specify too high a value for P the program might fail. If you
specify a value < 0 it will fail to compile.
Run this program using your favorite text file as input. Files such as mailboxes, man pages and usenet articles are especially recommended. You will get different output each time you run it.
This program implements an “Eddington ape” - it generates
random text from a supplied template. The template text file
is read through stdin. The larger the template, the better the
result. A maximum of 2**12 chars are used. From the template,
the program calculates the statistics of chars that immediately
follow a given string (correlator string) of a certain length
(currently 4 - can be varied by changing the definition for P
accordingly). A character is randomly chosen, weighted by its
probability to occur after the correlator string. That
character is printed to stdout and placed at the end of the
correlator string, whose first character is discarded.
Meaningful words are therefore usually preserved, the effect on
sentences can be dramatically random.
You might want to vary the definition of P between 2 and 10 and observe the result.
