When I first wrote the try scripts, and in particular the ovdluhe.alt.c code to do what the author suggested one try, I just had the option in try.alt.sh to redefine P once. Now the user can do that but after the initial loop it loops from 2..10 (the range the author suggested) running the loop again (on the three files three times) so one can see what the author means. The try.sh script has the updated idea by the judges of printing two lines, not one, after each prompt. Rebuilt index.html from updated README.md.

## To build:
|
|
|
|
``` <!---sh-->
|
|
make all
|
|
```
|
|
|
|
To get this to compile with a modern CPP, we had to replace `#D` with `#define`.
|
|
|
|
|
|
## To use:
|
|
|
|
Run the program this way:
|
|
|
|
``` <!---sh-->
|
|
./ovdluhe < textfile
|
|
```
|
|
|
|
The program stops when it reaches the end of the template buffer
|
|
by chance or is killed.
|
|
|
|
|
|
## Try:
|
|
|
|
``` <!---sh-->
|
|
./try.sh ; sleep 2 ; ./try.sh
|
|
```
|
|
|
|
|
|
## Alternate code:
|
|
|
|
The author suggested that one varies the definition of `P` from 2 through 10. As
|
|
it's a `#define` it's easy to set up.
|
|
|
|
|
|
### Alternate build:
|
|
|
|
``` <!---sh-->
|
|
make P=9 clobber alt
|
|
```
|
|
|
|
You 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 as will a
|
|
value that's not a number.
|
|
|
|
|
|
### Alternate use:
|
|
|
|
``` <!---sh-->
|
|
./ovdluhe.alt
|
|
```
|
|
|
|
|
|
### Alternate try:
|
|
|
|
``` <!---sh-->
|
|
./try.alt.sh
|
|
|
|
P=5 ./try.alt.sh
|
|
```
|
|
|
|
**NOTE**: if you specify too high a value for `P` the program might fail. If you
|
|
specify a value < 0 it will fail to compile.
|
|
|
|
The script will also run the program with `P=2` through `P=10` like the author
|
|
suggested. Send intr (usually ctrl-c) to stop early.
|
|
|
|
|
|
## Judges' remarks:
|
|
|
|
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.
|
|
|
|
|
|
## Author's remarks:
|
|
|
|
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.
