I had a program similar that gave averages and standard deviations.
However, if you are just trying to get a feel for things then perhaps
a graph would be better. So I whipped this up for you relatively quickly.
It will either do a statistical sample, like yours, or do an exaustive
population count (give it 0 for the samplesize).
Enjoy:
#!/usr/bin/perl -w
use strict;
my $dicemax = shift @ARGV || 6;
my $numdice = shift @ARGV || 6;
my $dicekeep = shift @ARGV || 6;
my $samplesize = shift @ARGV || 0;
my $totstates = $dicemax ** $numdice;
my $min = $dicekeep;
my $max = $dicekeep * $dicemax;
my $num = $max - $min + 1;
my @tot; @tot[$min..$max] = map {0} ($min..$max);
if ($samplesize) {
srand;
for my $x (1..$samplesize) {
my $sum=0;
$sum += $_ for (sort {$b<=>$a}
map {int rand($dicemax)+1} (1..$numdice)
)[0..$dicekeep-1];
$tot[$sum]++;
}
$totstates = $samplesize;
} else {
my $count = 0;
my @dice = map {1} (1..$numdice);
while ($count++ < $totstates) {
my $x = 0;
$dice[$x]++;
while ($dice[$x] > $dicemax) {
$dice[$x++] = 1;
$dice[$x]++;
}
my $sum=0;
$sum += $_ for (sort {$b<=>$a} @dice)[0..$dicekeep-1];
$tot[$sum]++;
}
}
my @per; @per[$min..$max] = map {$_/$totstates*100} @tot[$min..$max];
my $maxper = (sort {$b<=>$a} @per[$min..$max])[0];
print "Roll Percent| Frequency Graph (0 - $maxper%)\n";
for my $x ($min..$max) {
my $c = ($num-$x+$min)/$num*$maxper;
printf "%3d %5.2f | ", $x, $per[$x];
do { print $per[$_] > $c ? "*" : " " for ($min..$max) }
if $max-$min < 75;
print "\n";
}
print "-"x(16+$max-$min),"\n";
for my $x (100,10,1) {
print " "x14,map {int $_ / $x % 10} ($min..$max);
print "\n";
}

Are you posting in the right place? Check out Where do I post X? to know for sure.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
