What is Input/Output Logic? Input/Output Logic, Constraints, Permissions

چکیده
We explain the raison d’être and basic ideas of input/output logic, sketching the central elements with pointers to other publications for detailed developments. The motivation comes from the logic of norms. Unconstrained input/output operations are straightforward to define, with relatively simple behaviour, but ignore the subtleties of contraryto-duty norms. To deal with these more sensitively, we constrain input/output operations by means of consistency conditions, expressed via the concept of an outfamily. They also provide a convenient platform for distinguishing and analysing several different kinds of permission.

The Logic of Normative Systems
Logical architectures combine several logics into a more complex logical system. In this paper we study logical architectures using input/output operations corresponding to the functionality of logical components. We propose a logic of normative systems, based on an architecture of counts-as conditionals, institutional constraints, obligations and permissions. For counts-as conditionals and ins...

Logical architectures combine several logics into a more complex logical system. In this paper we study a logical architecture using input/output operations corresponding to the functionality of logical components. We illustrate how the architectural approach can be used to develop a logic of a normative system based on logics of counts-as conditionals, institutional constraints, obligations an...
متن کاملEfficient Delay Characterization Method to Obtain the Output Waveform of Logic Gates Considering Glitches
Accurate delay calculation of circuit gates is very important in timing analysis of digital circuits. Waveform shapes on the input ports of logic gates should be considered, in the characterization phase of delay calculation, to obtain accurate gate delay values. Glitches and their temporal effect on circuit gate delays should be taken into account for this purpose. However, the explosive numbe...
متن کاملPermissions and Undercutters
Input/output logics have been proposed to formalize rule based inference. They are mainly inspired by deontic logic, or the logic of obligations, although it has also been shown that they generalize for example Reiter’s normal default logic. A recent extension of the input/output logics formalizes various notions of permission. We are interested in the question whether input/output logics can b...
