Several decision procedures that were published in the last few years
for sub-theories of propositional linear inequalities, i.e., a Boolean
combination of predicates that belong to the theory, are based on a
graph-based analysis of the formula's predicates. The analysis is
always based on the predicates while ignoring the Boolean connectives
between them. In this note we show how taking this information into
account can significantly reduce the (practical) complexity of the
decision procedure.
