| abstract: |
Consider a set
S
of points in the plane in convex position, where each
point has an integer label from
{0,1,…,n-1}
. This naturally induces a labeling of the edges:
each edge
(i,j)
is assigned label
i+j
, modulo
n
. We propose the algorithms for finding large
non--crossing harmonic matchings or paths, i. e.
the matchings or paths in which no two edges have the same
label. When the point labels are chosen uniformly at
random, and independently of each other, our matching
algorithm with high probability (w.h.p.) delivers a
nearly--perfect matching, a matching of size
n/2 - O(n
.

The first source gives you the `gzipped' PostScript, the second the plain PostScript and the third the format for the Adobe accrobat reader. Depending on the installation of your web browser, at least one of these should (after some amount of time) pop up a window for you that shows the full article. If this is not the case, you should contact your system administrator to install your browser correctly.
Due to limitations of your local software, the two formats may show up differently on your screen. If eg you use xpdf to visualize pdf, some of the graphics in the file may not come across. On the other hand, pdf has a capacity of giving links to sections, bibliography and external references that will not appear with PostScript.
