Bibliography
Most of my work deals with equational theorem provers - especially
with the DISCOUNT
system developed at the Efficient
Algorithms Group
at the University of
Kaiserslautern and my own equational theorem prover E, which I build as part of the E-SETHEO
project sponored by the DFG under the grant
Je112/9-1.
I am particularly interested in finding out more about good proof
heuristics, and I work towards the automatic acquistion of search
control knowledge for deductive systems. Thus, much of my research has
to do with (deductive) reasoning and with (inductive) machine
learning.
Publications are listed in chronological order (I hope).

described in the paper has mutated into the full blown
probabilistic expert system PIT, with which I am
still loosely associated.

Presentations
I only make presentations availabe for major talks, and only if there
is no associated paper. If you want any of my other presentations,
feel free to ask (but I suggest you read the paper instead). In case
you are interested: I now prepare all my slides using
pdflatex and some modified style files originally borrowed
from Matt
Welsh.
