Add try scripts to 2018/ferguson + formatting
The try.sh and try.alt.sh scripts are respectively for the entry and the alt code. There is a joke in them that is based on what the judges originally suggested one try. The weasel.man page was deleted. Instead weasel.1 has had the FILES section removed (which caused some confusion in another way with another winner of that year). The spec file will have to be tested again another time. I did NOT format / typo check the README.md file. Too much to do for now and since it's mine I can do it any other time. I'd like to get through the rest of the entries. Thus this should complete (for now?) 2018/ferguson.

.SH DESCRIPTION
|
||||
\fBweasel\fP is an obfuscated implementation of Richard Dawkins' \fIWeasel program\fP.
|
||||
According to Wikipedia in chapter three of his book \fIThe Blind Watchmaker\fP Dawkins wrote:
|
||||
.PP
|
||||
.RS
|
||||
I don't know who it was first pointed out that, given enough time,
|
||||
a monkey bashing away at random on a typewriter could produce all
|
||||
the works of Shakespeare. The operative phrase is, of course, given
|
||||
enough time. Let us limit the task facing our monkey somewhat.
|
||||
Suppose that he has to produce, not the complete works of Shakespeare
|
||||
but just the short sentence 'Methinks it is like a weasel', and we
|
||||
shall make it relatively easy by giving him a typewriter with a
|
||||
restricted keyboard, one with just the 26 (capital) letters, and
|
||||
a space bar. How long will he take to write this one little sentence?
|
||||
.RE
|
||||
.PP
|
||||
He refers to the \fIInfinite Monkey Theorem\fP in particular and as he
|
||||
points out it is \fBgiven enough time.\fP The weasel program uses a \fIgenetic
|
||||
algorithm (GA)\fP to intelligently come to a conclusion but this implementation
|
||||
has several additions: \fBtwo Easter eggs,\fP a \fBquiet output mode,\fP
|
||||
an \fBoption to change the mutation rate\fP as well as the ability to
|
||||
\fBspecify the chromosomal string.\fP
|
||||
Furthermore the keyboard isn't as limited as Dawkins's implementation.
|
||||
The \fBweasel.alt\fP keyboard is a more limited keyboard but not
|
||||
as limited as Dawkins's Weasel program keyboard.
|
||||
.SH OPTIONS
|
||||
.PP
|
||||
\fB\-r\fP\fI<rate>\fP
|
||||
This sets the mutation rate to \fI<rate>\fP; valid range is 1 through 100.
|
||||
Anything outside this range will disable the genetic algorithm and simulate
|
||||
a monkey in front of a typewriter.
|
||||
If a valid mutation rate is set after this then the monkey typewriter mode
|
||||
will be disabled but if monkey mode has been explicitly requested by the
|
||||
\fB\-m\fP option the mutation rate is ignored.
|
||||
Note that there cannot be a space between the \fB\-r\fP and \fI<rate>\fP.
|
||||
The default is 1; valid range is >= 1 && <= 100.
|
||||
.PP
|
||||
\fB\-m\fP
|
||||
Set monkey mode. This disables the genetic algorithm and is disables the
|
||||
mutation rate entirely; instead it will pseudo-randomly select a character
|
||||
from the keyboard in every offspring for every generation and selection
|
||||
will not take place: parents are simply the first two offspring
|
||||
regardless of their fitness score. Once this is enabled you
|
||||
cannot disable it: be wary of the typing monkeys!
|
||||
.PP
|
||||
\fB\-q\fP
|
||||
Quiet output.
|
||||
Only display settings like mutation rate, quiet output,
|
||||
target string and the final answer - if it comes to one.
|
||||
Just like monkey mode you cannot disable this once it's been enabled.
|
||||
.PP
|
||||
\fB--\fP
|
||||
Disable parsing of additional options (but not target strings); see
|
||||
.B EXAMPLES
|
||||
for a subtle point.
|
||||
.SH EXIT STATUS
|
||||
On error of any kind (including reaching the maximum number of attempts)
|
||||
return 1; otherwise return 0.
|
||||
.SH BUGS
|
||||
Bugs? What's this? :) Any bugs are actually insolent monkeys tampering
|
||||
with the program! But if you insist I do include errata on my website.

\fBweasel \-m 'I AM A MONKEY TYPING'\fP

|

Simulate a monkey typing at the typewriter trying to type out the
|
||||
string \fBI AM A MONKEY TYPING\fP without quotes. Note that this will
|
||||
take some time almost assuredly and you might fall asleep before
|
||||
the monkey succeeds. Here you would see all the attempts because
|
||||
quiet output was not requested.

||||
.PP
|
||||
\fBweasel I AM NOT A MONKEY\fP
|
||||
.PP
|
||||
.NF
|
||||
Using the GA find the final string specified (this always happens);
|
||||
because the string wasn't quoted the program will have seen each word
|

as a separate argument and thus it would search for \fBMONKEY\fP.
