With the notable exception of abstract, Coq’s standard collection of tactics are free from side effects. In this talk, I propose to make the case that additional tactics with limited side effects that are “local” to a given proof can have a considerable impact on performance, presenting as evidence a set of ML tactics that have been developed as part of the Fiat deductive synthesis framework. I...

A 4-year research project was initiated during the 2002 growing season to evaluate, on a regional scale, pest management systems based on reduced-risk tactics that previous research and experience had indicated would be effective, sustainable, economically viable, and lead to enhanced biological control. The participating states are: Michigan, New Jersey, New York, North Carolina, Pennsylvania,...

Evidence for carcass access times and levels of early hominid mobility is synthesized using studies of carnivore ethology and theories of interspecific competition to arrive at tentative conclusions about the organization of Plio-Pleistocene hominid foraging groups. The model presented suggests that group foraging tactics, in combination with high mobility, are central to successful confrontati...

The type of tactics in all (procedural) proof assistants is (a variant of) the one introduced in LCF. We discuss why this is inconvenient and we propose a new type for tactics that 1) allows the implementation of more clever tactics; 2) improves the implementation of declarative languages on top of procedural ones; 3) allows for better proof structuring; 4) improves proof automation; 5) allows ...

In this paper we investigate group maintenance behavior in community-based Free/Libre Open Source Software (FLOSS) development teams. Adopting a sociolinguistic perspective, we conceptualize group maintenance behavior as interpersonal communication tactics—specifically, social presence and politeness tactics—that help maintain relationships among group members. Developer email messages were col...

This paper tries to de-mystify the urban legends and expose the secrets of success of those who excel at online tactical first-person shooters. It focuses specifically on the evolution of winning tactics, and postulates the existence of a special sort of tactic – the neo-tactic – which exploits the underlying low-level physics properties of the virtual environment. Such tactics may only be empl...

We present a comprehensive set of tactics that make it practical to use separation logic in a proof assistant. These tactics enable the verification of partial correctness properties of complex pointer-intensive programs. Our goal is to make separation logic as easy to use as the standard logic of a proof assistant. We have developed tactics for the simplification, rearranging, splitting, match...

This paper presents a quality-driven approach to embodying non-functional requirements (NFRs) into software architecture using architectural tactics. Architectural tactics are reusable architectural building blocks, providing general architectural solutions for common issues pertaining to quality attributes. In this approach, architectural tactics are represented as feature models, and their se...

A measure of Facebook-related mate-retention tactics was developed to investigate the relationship between online behaviors and intimate partner aggression. One hundred and seventy-seven young adults (65 men, 112 women) completed questionnaires that included measures of online and offline mate-retention tactics, Facebook jealousy, Facebook surveillance, and intimate partner violence. A factor a...
