<blockquote class="uncited"><div>Hi guys, looking for the paper that introduced the concept of islands or explains them in enough depth to act as a reference.  so far I haven't had much joy :/</div></blockquote>Slow response on an old thread here, but maybe it is of interest to someone...<br><br>You can also look for splitting and blocking methods, and perhaps also spectral analysis in numerical linear algebra. This is about finding disconnected or weakly connected blocks in a large system of equations (i.e. a matrix problem), and as mentioned, this is often done using graph traversals.<br><br>These blocks or "islands" can then be solved independently and coupled using additive Schwarz.<p>Statistics: Posted by <a href="https://pybullet.org/Bullet/phpBB3/memberlist.php?mode=viewprofile&amp;u=1339">KenB</a> — Fri Aug 29, 2008 3:54 pm</p><hr />
