The Computational Complexity of Inference Using Rough Set Flow Graphs
Pawlak recently introduced rough set flow graphs (RSFGs) as a graphical framework for reasoning from data. Each rule is associated with three coefficients, which have been shown t...

Inferential Complexity Control for Model-Based Abduction
We describe a technique for speeding up inference for model-based abduction tasks that trades off inference time and/or space for the fraction of queries correctly answered. We co...

Fast alignment of a complex tracking detector using advanced track models
The inner silicon detector of the Compact Muon Solenoid experiment (CMS) at CERN’s LHC consists of 16 588 modules. Charged-particle tracks in the detector are used to improve th...

SRIQ and SROIQ are Harder than SHOIQ
We identify the complexity of (finite model) reasoning in the DL SROIQ to be N2ExpTime-complete. We also prove that (finite model) reasoning in the DL SR--a fragment of SROIQ witho...

The Complexity of Logic-Based Abduction
Abduction is an important form of nonmonotonic reasoning allowing one to find explanations for certain symptoms or manifestations. When the application domain is described by a l...
