<h1>Known Bugs</h1>
|
|
|
|
There are likely a <em>whole host</em> of bugs and issues with this software -- it should be considred "Beta" for the moment. Here are
|
|
the ones we know about:
|
|
|
|
<ul>
|
|
|
|
<li> <del> DeleteMin fails on a heap with a single element. </del></li>
|
|
<ul>
|
|
<li> Fixed on 12/19/2013 </li>
|
|
</ul>
|
|
<li> <del>None of the visualizations work for older versions of explorer </del> </li>
|
|
<ul>
|
|
<li> Fixed on 8/23/2012. Thanks to Stefan German for fiding this one.</li>
|
|
</ul>
|
|
|
|
|
|
|
|
<li> <del>Putting a semicolon in any of the input fields causes the application to die </del> </li>
|
|
<ul>
|
|
<li> Fixed on 5/3/2011. Semicolons can no longer be entered. Thanks to Stefan German for fiding this one.</li>
|
|
</ul>
|
|
<li> <del>BST and AVL trees have broken undos in HTML5 version</del></li>
|
|
<ul>
|
|
<li> Fixed on 5/3/2011.</li>
|
|
</ul>
|
|
|
|
<li> <del>Find and Delete broken in open hashing
|
|
|
|
</del></li>
|
|
<ul>
|
|
<li> Fixed on 5/10/2011. (thanks to Eduardo Bonet, of Santa Catarina Federal University, Brazil, for finding this one!)</li>
|
|
</ul>
|
|
|
|
|
|
|
|
<li> All algorithms that compute an ordering (BST, AVL Trees, etc) don't sort floating point numbers correctly -- 9.2 > 10.3 </li>
|
|
<ul>
|
|
<li> This one is a design decision -- since those algoritms can take <em>any</em> string, the decision was made to sort based on lexicographic order.
|
|
We tried to mitigate confusion somehwat by automatically converting positive integers into equivalent numbers with leading zeroes, so that positive
|
|
integers would always be ordered as expected (though negative numbers are alas off). It turns out that if you are trying to sort a group of any strings,
|
|
using a mixed comparison strategy gets confusing
|
|
fast -- how should 10.4 compare to 3.1.2? What about 3A -- is that a string or a hexidecimal number?
|
|
What about AF? Should BC come before or after AFF? We made the executive decision to just do string comparisons.
|
|
</ul>
|
|
<li> <del> When running connected components, if you run the algorithm, then undo, then run it again, the application breaks. We're working on a fix --
|
|
the current workaroud is to create a new graph after undo before running the algorithm again.</del></li>
|
|
<ul>
|
|
<li> Fixed on 5/10/2011.</li>
|
|
</ul>
|
|
|
|
|
|
<li> <del>Undoing deleting an element from a B-Tree or B+ tree broken
|
|
|
|
</del></li>
|
|
<ul>
|
|
<li> Fixed on 6/13/2011.</li>
|
|
</ul>
|
|
|
|
|
|
<li> <del>Radix sort broken on Safari browser
|
|
|
|
</del></li>

<ul>

|
|
<li> Various typos </li>
|
|
<ul>
|
|
<li> Please continue to send in any typos you see, and I will correct them as I get to them (at a somewhat lower priority than functionaility
|
|
bugs, of course). Typo corrections will not appear on this page.
