<h2>About</h2>
|
||||
<p>This is an upload form for the <a href="https://github.com/tgorordo/carousel">carousel</a> stable matcher for ,
|
||||
mainly to help with <a href="https://blogs.uoregon.edu/physicsgsg/">UO Physics TA assignments</a>.
|
||||
This form uses the <a href="https://service.uoregon.edu/TDClient/2030/Portal/KB/ArticleDet?ID=43069">UO pages.uoregon.edu CGI Capability</a>,
|
||||
so the implementation of smithy being invoked can be <a href="https://pages.uoregon.edu/tgorordo/files/carousel/"> inspected here</a>
|
||||
and you may also inspect the source of this page to verify that <a href="https://pages.uoregon.edu/tgorordo/files/carousel/src/cgi/carousel.cgi?source">this script<a> is called to invoke it - though
|
||||
you have to trust it to <a href="https://en.wikipedia.org/wiki/Quine_(computing)">quine</a> itself faithfully.
|
||||
</p>
|
||||
|
||||
<p> A <a href=https://en.wikipedia.org/wiki/Stable_matching_problem>stable matching (of the "college admissions" problem)</a> is one in which there is no pair of, say, TA and course which would prefer
|
||||
each other over their respective assignment given by the matching. This form runs a version of the
|
||||
<a href="https://en.wikipedia.org/wiki/Gale%E2%80%93Shapley_algorithm">Gale-Shapley (1962) deferred-acceptance algorithm</a>, which finds the stable matching
|
||||
that is optimal for the TA preferrences. Other stable solutions can be found by using <a href="https://github.com/tgorordo/carousel">the underlying
|
||||
python application manually</a>.
|
||||
</p>
|
||||
|
||||
|
||||
<h3>Tabular Input</h3>
|
||||
You can enter tables of preferences directly in the first tab of the form above.
|
||||
|
||||
TODO
|
||||
|
||||
<h4>Example:</h4>
|
||||
Suppose we want to figure out a Grad TA-to-Class assignment. Graduate students will be our "Applicants"
|
||||
- each one will be assigned a class to TA -, and classes will be our "Reviewers" - taking a quota of needed TAs.
|
||||
|
||||
TODO
|
||||
|
||||
<h3>File Upload</h3>
|
||||
|
||||
For more complicated input, a file upload might be preferable to table form submission
|
||||
(e.g. if there's a validation issue you won't have to manually re-enter the table, just tweak and re-upload the file).
|
||||
