Sorry if this is slightly off-topic, but what is wrong with IComparer?

I would guess that it's because a .Net interface (or a .Net anything) is normally not seen on this blog. See the tagline at top right! :-)

The solution to the IComparer for Tasks is too compare another task field after the dependency comparison showed nothing. For instance: int compare(Task a, Task b) { if (a.dependsOn(b)) return 1; if (b.dependsOn(a)) return -1; return strcmp(a.getName(), b.getName()); // or return a.getId() - b.getId(); if you don't like the sort order depending on the task name which could change. }

Sorry, Jonathan, that still doesn't work. Consider this dependency diagram: c -> a b then a<b (no dependency, use alpha sort), and b<c (no dependency, use alpha sort), and c<a (dependency).

raymond, you are wrong, "b<c" is incorrect because there IS a dependency of c on b ... dependencies are by definition bi-directional.

The conversion from gotdotnet messed up the formatting. The diagram should be

c -> a
b

there is no dependency betwen b and anything.

With that I'm closing comments since this thread is extremely old.
