Publications

• Here is the list of my publications many of which are available online.
• A similar list is administrated by our laboratory.
• Other sources: DBLP bibliography server (University of Trier).

Research

• My research interests include
  • Knowledge representation and reasoning
  • Nonmonotonic logics and their expressive power
  • Logic programming and answer set programming (ASP)
  • Verifying equivalence of answer set programs
  • Software engineering aspects of ASP (modularity, optimization, etc)
  • Distributed computing of answer sets (multiprocessor architectures, computational grids)
  • Satisfiability checking and its relationship to ASP
  • Computational complexity
• Research projects (after year 2000): MCM, ACPT, ARBCP, FMDS, CPBDR, and 007
• Experimental software and tools: GnT, lpeq, circ2dlp, lp2sat, sateq, and asptools
• Educational software: the Stratum system for automated home assignments
