This article is published with open access at Springerlink.comAbstract Formal verification aims to enhance the quality of software program by detecting errors ahead of they do harm. At the basis of formal verification is the logical notion of correctness, which purports to capture whether or not a plan behaves as desired. We suggest that the boolean partition of software into right and incorrect programs falls quick in the sensible have to have to assess the behavior of application in a more nuanced fashion against various criteria. We hence propose to introduce quantitative fitness measures for programs, specifically for measuring the function, performance, and robustness of reactive applications such as concurrent processes. This article describes the targets of the ERC Advanced Investigator Project QUAREM. The project aims to make and evaluate a theory of quantitative fitness measures for reactive models. Such a theory need to strive to get quantitative generalizations on the paradigms which have been accomplishment stories in qualitative reactive modeling, including compositionality, property-preserving abstraction and abstraction refinement, model checking, and synthesis. The theory will probably be evaluated not just inside the context of software and hardware engineering, but also within the context of systems biology. In certain, we’ll use the quantitative reactive models and fitness measures created in this project for testing hypotheses about the mechanisms behind information from biological experiments.

The project aims at rebuilding a central part of the formal foundation of computing by replacing the classical, boolean notion of plan correctness having a new, quantitative measure of program fitness. Inside the platonic, boolean world of classical SPQ web computer science, applications can only be correct or incorrect.1 Within the genuine globe, one particular plan is typically preferred more than a further, even though both are technically right (for example, one particular may very well be more robust against faulty inputs than the other), or if both are technically incorrect (a single may misbehave significantly less often, or much less severely, than the other). Such behavioral preferences could be formalized by quantitative measures of fitness between programs and specifications. We think that by putting the formal modeling of computational processes on a quantitative foundation, we can pave the way for an elevated use of such models, not only in computer software and technique improvement but in addition inside the all-natural sciences. In certain, in biology the usage of computational models for testing mechanistic hypotheses has been hampered by the lack of quantitative measures of fitness in between models and experimental information. 1.1 From proving program correctness to measuring technique fitness Discrete pondering has dominated laptop or computer science from its incredibly beginnings and is, actually, what distinguishes laptop science from most other engineering disciplines. This really is because every single digital computational course of action may be idealized1 The platonic view of applications.
