|
||
<p>We recommend that you try the alternate version first so you can see what this
|
||
entry looked like back in 1995 (with a configurable speed). See the <a href="#original-code">original
|
||
code</a> section below for the original entry.</p>
|
||
<div class="sourceCode" id="cb1"><pre class="sourceCode sh"><code class="sourceCode bash"><span id="cb1-1"><a href="#cb1-1" aria-hidden="true" tabindex="-1"></a><span class="fu">make</span> alt</span></code></pre></div>
|
||
<p>The alternate version uses <code>usleep(3)</code> with <code>SLEEP</code> (defined in the Makefile,
|
||
default <code>3000</code>) microseconds to make it easier to see the maze being solved in
|
||
real time. You can redefine <code>SLEEP</code> at compile time to reconfigure it in case
|
||
it’s going too slow, too fast :-) or you’re doing some strange experiment like
|
||
making it 100000 (which is actually fun :-) ).</p>
|
||
<h3 id="bugs-and-misfeatures">Bugs and (Mis)features:</h3>
|
||
<p>The current status of this entry is:</p>
|
||
<pre><code>STATUS: INABIAF - please **DO NOT** fix</code></pre>

<span id="cb4-3"><a href="#cb4-3" aria-hidden="true" tabindex="-1"></a><span class="ex">./cdua.alt</span> <span class="co"># press enter and watch it go much faster!</span></span></code></pre></div>
|
||
<p>You might also like to try:</p>
|
||
<div class="sourceCode" id="cb5"><pre class="sourceCode sh"><code class="sourceCode bash"><span id="cb5-1"><a href="#cb5-1" aria-hidden="true" tabindex="-1"></a><span class="fu">make</span> SLEEP=65000 clobber alt</span>
|
||
<span id="cb5-2"><a href="#cb5-2" aria-hidden="true" tabindex="-1"></a></span>
|
||
<span id="cb5-3"><a href="#cb5-3" aria-hidden="true" tabindex="-1"></a><span class="ex">./cdua.alt</span> <span class="co"># press enter and watch it go much slower!</span></span></code></pre></div>
|
||
<p>Do you see anything strange in this version when <code>SLEEP</code> is a high value like
|
||
<code>65000</code>? What happens if you use <code>100000</code>? Is this strange output still there?
|
||
Why?</p>
|
||
<h2 id="original-code">Original code:</h2>
|
||
<p>With modern systems this was hard to see it solve it in real time because it
|
||
goes so quickly which is why we recommend the alternate version first: you can
|
||
actually see it being solved in real time rather than have it go by in a flash.</p>
|
||
<p>If you wish to use the original version, for instance if you wish to see how
|
||
fast your computer is :-) or use both to see the difference, you can do so.</p>

<h2 id="judges-remarks">Judges’ remarks:</h2>
|
||
<p>This could be used as the basis of an a-maze-ing screen exerciser.</p>
|
||
<h2 id="authors-remarks">Author’s remarks:</h2>
|
||
<p>A program that generates a maze, and then solves it, all this being seen by the
|
||
user. Some highlights of obfuscation are: 3 step function in one - <code>main()</code>,
|
||
several recursive calls with conditional actions, and just one (big and ugly)
|
||
statement to solve the maze.</p>
