<p class=MsoNormal style='margin-bottom:12.0pt'><font size=3

<br>
Looking at the approach and capabilities of the GReAT toolchain, it seems like
you would want to have some common algorithmic idioms.&nbsp; I'm thinking of
things like finding disjoint subgraphs or spanning trees.&nbsp; One of the
examples also mentioned topological sort. I'm stretching a little here since I
haven't used the tool, but this is a journey of understanding.&nbsp;&nbsp; Is
there a way to do that sort of thing generically for different metamodels, or
are things like that even useful in practice?&nbsp; Or rather, have I missed
something regarding the approach? <br>
<br>
Hopefully all of you that use GReAT on a regular basis can steer me in the
right direction.<br>
<br>
Thanks,<br>
