Welcome to Taniquetil, Eldaran's home!
Well, we are not so high... yet. So welcome at least to homepage of
Robert Cimrman.

I am a PhD student of Applied Mechanics at the University of West Bohemia
in Plzeň, Czech Republic. My official field of interest is biomechanics,
particularly mathematical modelling of smooth muscle tissues. You can look at
my (unfinished, unfinnished too) CV.

Some latest (16.07.2001) outputs of work I participate in can be found in
results directory.
There is a special campaign here, but
it is only for invited. Invited are all who understand this:
Aby si anglicky mluvící moc nevyskakovali, napsal jsem také něco česky.
Ať mají zlost, že nerozumí :-). No, pravý důvod pro užití češtiny je ten,
že zmíněná kampaň se týká pouze občanů České republiky.
Proto občane, následuj odkaz! (To zní ale blbě. Čí odkaz? Lenina? Asi...)
Pokud vás zajímají příklady, které se zatím dělaly na MVS (matematické
výpočtové systémy, aka matlab), následujte link.
Budou tam i zadání semestrálek. Oficiální stránky jsou tady.
Local Mind Algorithm Projections
This majestic title means that a list follows of all the nonsenses I have coded
so far. In fact, all stuff here is a result of the real-work-aversion,
too-much-forced-free-time or never-be-adult-approach. I have created as well
many tools (including a FEM package) supporting my work, but they
are all strictly confidential (read: not finished, buggy and hardly usable
for anybody else).

ma2ze is a 3D maze written in the matlab language. Its page is
here.
-
CAFire has its own page here. If you have
always dreamt about a burning mouse pointer in your X, this is something for
you.

Elwing is a parallel conjugate gradient solver written from scratch in
one week. Current implementation uses MPI, but you can use whatever you like -
the only thing to do is to write your own "itc.c". Since I was under
lack-of-time pressure (never used MPI before), there are some shortcomings or
inefficiencies still lurking here. The biggest of them is a memory wasting due
to storing both triangles of a symmetrical matrix - the matrix distribution is
rather complex even in this case. However it can be rather easily fixed and
works quite well: a pentadiagonal system of 1.000.000 equations was solved on
one of our university clusters (6 Linux PC on Myrinet) in about 7 seconds. Yes,
the matrix was _really_ well conditioned :-), but 3 iterations in less then 1
second is not bad. You can check some performance
statistics, or download it and try it
yourself.

INM stays for Iterative Numerics Magic. I created this when assisting in
Numerical Methods lessons. It displays Newton fractal set and requires Qt
library. I wrote it basically to see what the hell is going on in fractal and
convergence stuff, that it produces so nice pictures. You can get it here. It has a rather convenient GUI and is not so
bad, but if you want something really _good_ and _fast_, get XaoS. It is the best fractal
beast I have ever seen.

More comes later, after I fight laziness.
