Abstract
Summary form only given. We briefly present a rule-based framework, called EAGLE, shown to be capable of defining and implementing finite trace monitoring logics, including future and past time temporal logic, extended regular expressions, real-time and metric temporal logics (MTL), interval logics, forms of quantified temporal logics, and so on. In this paper we focus on a linear temporal logic (LTL) specialisation of EAGLE. For an initial formula of size m, we establish upper bounds of O(m/sup 2/2/sup m/logm) and O(m/sup 4/2/sup 2m/log/sup 2/m) for the space and time complexity, respectively, of single step evaluation over an input trace. EAGLE has been successfully used, in both LTL and metric LTL forms, to test a real-time controller of an experimental NASA planetary rover.
