On Efficient Reasoning with Implication Constraints
- IN DOOD
, 1993
"... In this paper, we address the complexity issue of reasoning with implication constraints. We consider the IC-RFT problem, which is the problem of deciding whether a conjunctive yes/no query always produces the empty relation ("no" answer) on database instances satisfying a given set of ..."

In this paper, we address the complexity issue of reasoning with implication constraints. We consider the IC-RFT problem, which is the problem of deciding whether a conjunctive yes/no query always produces the empty relation ("no" answer) on database instances satisfying a given set
Implications of rational inattention
- JOURNAL OF MONETARY ECONOMICS
, 2002
"... A constraint that actions can depend on observations only through a communication channel with finite Shannon capacity is shown to be able to play a role very similar to that of a signal extraction problem or an adjustment cost in standard control problems. The resulting theory looks enough like fa ..."

Implicational Constraints, Defaults and Markedness *
"... Once Prince & Smolensky (1993) set the theoretical underpinnings of Optimality Theory (OT), the organization and structure of the collection of universal constraints CON soon became a topic of some debate. One of the points that has received some attention has been the possibility to extend CON ..."

Learnability in Optimality Theory
, 1995
"... In this article we show how Optimality Theory yields a highly general Constraint Demotion principle for grammar learning. The resulting learning procedure specifically exploits the grammatical structure of Optimality Theory, independent of the content of substantive constraints defining any given gr ..."

Stability properties of constrained queueing systems and scheduling policies for maximum throughput in multihop radio networks
- IEEE Transactions on Automatic Control
, 1992
"... Abstruct-The stability of a queueing network with interdependent servers is considered. The dependency of servers is described by the definition of their subsets that can be activated simultaneously. Multihop packet radio networks (PRN’s) provide a motivation for the consideration of this system. We ..."

. We study the problem of scheduling the server activation under the constraints imposed by the dependency among them. The performance criterion of a scheduling policy m is its throughput that is characterized by its stability region C,, that is, the set of vectors of arrival rates for which the system
A framework for information systems architecture.
- IBM Syst. J.,
, 1987
"... With increasing size and complexity of the implementations of information systems, it is necessary to use some logical construct (or architecture) for defining and controlling the interfaces and the integration of all of the components of the system. This paper defines information systems architect ..."

Also, some preliminary conclusions about the implications of the resultant descriptive framework
Binary Equality Implication Constraints, Normal Forms and Data Redundancy Abstract
"... We define binary equality implication constraints (BEICs) in relational databases and study the implication problem of these constraints, in particular, we provide a sound and complete set of inference rules for a common subset of BEICs. Two normal forms with respect to BEICs are defined and shown t ..."

Constraints on Short-selling and Asset Price Adjustment to Private Information
- Journal of Financial Economics
, 1987
"... This paper models effects of short-sale constraints on the speed of adjustment (to private information) of security prices. Constraints eliminate some informative trades, but do not bias prices upward. Prohibiting traders from shorting reduces the adjustment speed of prices to private information, e ..."

Solutions of Implication Constraints yield Type Inference for More General Algebraic Data Types
, 2005
"... We study an extension of Hindley/Milner with a user-programmable constraint domain and a general form ofalgebraic data types which unifies common forms such as existential types, the combination of type classes and existential types and the more recent extension of guarded recursive data types. We ..."
