Abstract
In [1] we proposed to verify LTL properties using a fine grain analysis classifying formulae into four classes (stutter, shortening, lengthening insensitive or none of these). With this classification we extend the applicability of structural reduction to two new classes of formulas, when classical techniques are only applicable for stutter insensitive formulas. This comes at the price of a semi-decision procedure where only some verdicts are reliable.
In this paper, we present an implementation of this approach, built as an extension to the ITS-Tools model-checker that relies on the Spot library to analyze automata. This new approach significantly improves the ITS-tools model-checker when verifying properties that are not stutter insensitive. It can also be used as a front-end simplification step for any other model-checker.

Science of Computer Programming is dedicated to the distribution of research results in the areas of software systems development, use and maintenance, including the software aspects of hardware design.
The journal has a wide scope ranging from the many facets of methodological foundations to the details of technical issues andthe aspects of industrial practice.
The subjects of interest to SCP cover the entire spectrum of methods for the entire life cycle of software systems, including
• Requirements, specification, design, validation, verification, coding, testing, maintenance, metrics and renovation of software;
• Design, implementation and evaluation of programming languages;
• Programming environments, development tools, visualisation and animation;
• Management of the development process;
• Human factors in software, software for social interaction, software for social computing;
• Cyber physical systems, and software for the interaction between the physical and the machine;
• Software aspects of infrastructure services, system administration, and network management.
