A Short Story of a Subtle Error in LTL Formulas Reduction and Divine Incorrectness
arXiv:1011.4214
Abstract
We identify a subtle error in LTL formulas reduction method used as one optimization step in an LTL to Büchi automata translation. The error led to some incorrect answers of the established model checker DiVinE. This paper should help authors of other model checkers to avoid this error.
