I use Mathematica mainly for enjoyment, although it has been enormously
helpful for me in areas such as probability, statistics and actuarial
science related problem-solving with simulation techniques; big file
handling; data analysis; textual analysis, and a lot of other things.
In particular, I have nothing to do with computer-science related problems,
but if you look at one of the add-on packages in Mathematica, namely
DiscreteMath`Combinatorica`, you'll find there a prodigious amount of
material related to graph and network problems. I can refer, for example, to
functions such as  ShortestPath,  BipartiteMatching, MaximalMatching, and
NetworkFlow, which at least in their names seem to correspond to the
problems you mention.
As for the other field, I suggest you look at the add-on package
DiscreteMath`ComputationalGeometry`, where you'll find functions such as
ConvexHull,  DelaunayTriangulation and VoronoiDiagram. There is also a
splendid book by Tom Wickham-Jones, "Mathematica Graphics", which contains a
collection of related packages,  such as ExtendGraphics`SimpleHull` and
ExtendGraphics`Delaunay`, among others.
To answer your last question, the packages are already there, but I don't
think that is reason enough for me to go into that kind of problems (too
complicated).
