On the optimal approximation of operators

USSR Computational Mathematics and Mathematical Physics, 1977
Abstract We pose the problem of approximating optimally the values of an unbounded operator, using elements which are specified solely by the traces (values) of some operator. Estimates are obtained for the accuracy of the optimal approximation, linear optimal algorithms are found in explicit form, and their structures are examined, and the optimal ...

UPC Collective Operations Optimization

2007
In any parallel programming language; collective communication operations involve more than one thread/process and act on multiple streams of data. The language's API provides both algorithmic and run-time system support to optimize the performance of these operations.

Approximation operators in optimization theory

Zeitschrift für Operations Research, 1981
Recently, new types of tangential cones such as the radial tangent cone, the hypertangent cone, the Clarke's tangent cone, and the set of directions in which a set is epi-Lipschitzian at a point have been introduced by Clarke, Hiriart-Urruty, and Rockafellar.

On the optimality of rank order operations

ICASSP '86. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
With the aid of the threshold decomposition, rank order filters are shown to be the optimal filters under a general error criterion which includes an absolute error criterion. The particular rank order filter that is optimal is specified by a linear program.

Operations Research and Optimal Radiology

Radiology, 1959
Operations research is a novel approach to the problem of making sound decisions in complex matters. Conceived during the last war by scientists helping the war effort, it has proved its usefulness in many fields, as different as hunting enemy submarines and determining optimal rates of industrial production.

Optimization Challenges in Smart Grid Operations

2012
A smart grid is the combination of a traditional power distribution system with two-way communication between suppliers and consumers. While this communication is expected to deliver energy savings, cost reductions and increased reliability and security, smart grids bring up challenges in the management of the power system, such as integrating ...
