Approximation techniques for utilitarian mechanism design
Proceedings of the thirty-seventh annual ACM symposium on Theory of computing, 2005This paper deals with the design of efficiently computable incentive-compatible mechanisms for combinatorial optimization problems with single-minded agents each possibly having multiple private parameters. We focus on approximation algorithms for NP-hard mechanism design problems.

Designs for crossvalidating approximation models
Biometrika, 2013Multifold crossvalidation is routinely used for assessing the prediction error of an approximation model for a black-box function. Despite its popularity, this method is known to have high variability. To mitigate this drawback, we propose an experimental design approach that borrows Latin hypercube designs to construct a structured crossvalidation ...

Approximating Behaviors in Embedded System Design
2008Embedded systems are electronic devices that function in the contextof a physical environment, by sensing and reacting to a set of stimuli. To sim-plify the design of embedded systems, different parts are best described usingdifferent notations and analyze with different techniques, i.e., the system is saidto beheterogeneous. We informally refer to the

Approximate Perspective Design of Roads
Journal of Transportation Engineering, 1999Coordination of horizontal and vertical alignments is an important principle in road geometric design, and it should begin with preliminary design. Perspective drawings and sketches are considered to be effective means for evaluating this coordination.

Design of Approximate Restoring Dividers
2019 IEEE International Symposium on Circuits and Systems (ISCAS), 2019In this paper, two approximation models are proposed for restoring divider. In the first design, approximation is performed at circuit level, where exact restoring divider cells are replaced by approximate restoring divider cells by simplifying the logic equations. In the second model, restoring divider is analysed strategically and number of restoring

Magnetic spectrometers: approximate and ideal designs
Ultramicroscopy, 1976A produce for determining spectrometer parameters on the basis of specified criteria is illustrated by the design of an energy loss spectrometer for The John Hopkins University high resolution scanning transmission electron microscope. The design tutorial not only includes general expressions for uniform field magnets but also shows how published first

Towards Reversed Approximate Hardware Design
2018 21st Euromicro Conference on Digital System Design (DSD), 2018Approximate computing is an emerging design paradigm for trading off computational accuracy for computational effort. Due to their inherited error resilience many applications significantly benefit from approximate computing. To realize approximation, dedicated approximate circuits have been developed and provide a solid foundation for energy and time ...

The Design of Approximation Algorithms
2011Discrete optimization problems are everywhere, from traditional operations research planning (scheduling, facility location and network design); to computer science databases; to advertising issues in viral marketing. Yet most such problems are NP-hard; unless P = NP, there are no efficient algorithms to find optimal solutions.

Approximate Design of Digital Filters
Technometrics, 1965A simple type of digital filter for a sampled-data time series can be obtained by application of a linear recurrence relation. Properties of general linear recurrence relations are analysed in terms of the displacement operator E, although an equivalent analysis is possible using z-transform theory.
