‘è–ÚFGeneralized R-Calculus
yŠT—vz
Inference system for belief revision, one of the most efficient tools,
plays a significant role in the description of the process of
software evolution and scientific discovery.
This topic presents a generalization of the local inference system
R-calculus by allowing the formula set Gamma in a R-configuration
to be inconsistent. Four sets of rules, i.e.
GR-axioms, GR-logical connective symbol rules, GR-quantifier
symbol rules, and GR-cut rules, are analogously defined in this
paper, on the basis of the R-calculus language. Moreover, this
generalized R-calculus is proved sound and complete.
