Several [posts](https://mathoverflow.net/q/31545) (and [this](https://cs.stackexchange.com/q/41651/941)) on StackExchange sites like MO have some link-rot. For example, I've been looking into tree decomposition and keep coming across references to [treewidth.com](http://www.treewidth.com), but the link appears to be dead. Does any one have an update on this site to share?



Does anyone have the correct link to treewidth.com?
In situations like this, <https://archive.org> helps.


In this case check:


[https://web.archive.org/web/\*/http://www.treewidth.com/](https://web.archive.org/web/*/http://www.treewidth.com/)


There are many snapshots over time, though the downloads fail for me.


Searching for "libtw.jar", showed the same site at:
<http://treewidth.com/treewidth/index.html>


and libtw.zip is downloadable.
