Submissions should be in PDF and printable on US Letter.
To encourage authors to submit their best work, this year we are
encouraging shorter papers (around 6 pages, excluding references). This
is to allow authors to submit longer, revised versions of their papers
to archival conferences or journals. Longer papers (10--12 pages) are
also acceptable, if the extra space is needed. There is no maximum
length limit on submissions, but good submissions will likely be in the
range of 6 to 12 pages.
