## Abstract

The standard technique for LTL model checking ($M\models\neg\vi$) consists on translating the negation of the LTL specification, $\vi$, into a B\"uchi automaton $A_\vi$, and then on checking if the product $M \times A_\vi$ has an empty language. The efforts to maximize the efficiency of this process have so far concentrated on developing translation algorithms producing B\"uchi automata which are {\em as small as possible}'', under the implicit conjecture that this fact should make the final product smaller. In this paper we build on a different conjecture and present an alternative approach in which we generate instead B\"uchi automata which are {\em as deterministic as possible}'', in the sense that we try to reduce as much as we are able to the presence of non-deterministic decision states in $A_\vi$. We motivate our choice and present some empirical tests to support this approach.
