| abstract: |
In this paper we present an algorithmic approach to packing
A
-paths. It is regarded as a generalization of
Edmonds' matching algorithm, however there is the
significant difference that here we do not build up any
kind of alternating tree. Instead we use the so-called
3-way lemma, which either provides augmentation, or a dual,
or a subgraph which can be used for contraction. The method
works in the general setting of packing non-returning
A
-paths. It also implies an ear-decomposition of
criticals, as a generalization of the odd ear-decomposition
of factor-critical graph.

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.
