Contractor programming
This paper describes a solver programming method, called contractor programming, that copes with two issues related to constraint processing over the reals. First, continuous constraints involve an inevitable step of solver design. Existing softwares provide an insufficient answer by restricting users to choose among a list of fixed strategies. Our first contribution is to give more freedom in ...

This has led to renewed interest in the issue of when a worker is an employee vs. an independent contractor. The IRS must make determinations regarding worker status. This determination process which has evolved through judicial precedent, is subjectiv...
متن کاملPatterns of Onsite Magnetic Resonance Imaging Equipment among Orthopedic Practices
BACKGROUND Despite ongoing policy debate, little is known about the growth in orthopedic surgery practices with onsite magnetic resonance imaging (MRI) capacity, or practice characteristics associated with the acquisition of in-office MRI equipment. METHODS In July 2012, American Academy of Orthopaedic Surgeons (AAOS) member practices received a web-based survey requesting general information...
متن کاملNASA Contractor Report
This paper describes preconditioned conjugate gradient methods for solving sparse symmetric and positive definite systems of linear equations. Necessary and sufficient conditions are given for when these preconditioners can be used and an analysis of their effectiveness is given. Efficient computer implementations of these methods are discussed and results on the CYBER 203 and the Finite Elemen...
متن کاملDefining Contractor Performance Levels
In many countries, state and private owners often categorize contractors into various groups based on their capacities as well as their previous performance. These categories are then used for several purposes including contract award and prequalification. A number of different statistical algorithms can be used to categorize the contractors. No one algorithm can be used globally in all situati...
