Feedback-Directed Random Test Generation

29th International Conference on Software Engineering (ICSE'07), 2007
We present a technique that improves random test generation by incorporating feedback obtained from executing test inputs as they are created. Our technique builds inputs incrementally by randomly selecting a method call to apply and finding arguments from among previously-constructed inputs.

Feedback-directed specialization of code

Computer Languages, Systems & Structures, 2010
Based on feedback information, a large number of optimizations can be performed by the compiler. This information actually indicates the changing behavior of the applications and can be used to specialize code accordingly. Code specialization is a way to facilitate the compiler to perform optimizations by providing the information regarding variables ...

ParTool: A Feedback-Directed Parallelizer

2011
We present a tool which gives detailed feedback to application developers on how their programs can be made amenable to parallelization. Also, the tool automatically parallelizes the code for a large number of constructs. Since the tool outputs a parallelized code with OpenMP pragmas, the feedback cycle can be run any number of times till the desired ...

Feedback directed implicit parallelism

ACM SIGPLAN Notices, 2007
In this paper we present an automated way of using spare CPU resources within a shared memory multi-processor or multi-core machine. Our approach is ( i ) to profile the execution of a program, ( ii ) from this to identify pieces of work which are promising sources of parallelism, (

DIRECT FEEDBACK IN AUTOMATA NETWORKS

IFAC Proceedings Volumes, 2005
Abstract This paper investigates the problem posed by direct feedback in automata networks. Such a feedback introduces a direct instantaneous depending of the input of a system upon itself through a signal path within the network. In continuous system theory such a feedback yields an algebraic loop, which may render the overall system ill-posed.

A high-directivity microstrip directional coupler with feedback compensation

2002 IEEE MTT-S International Microwave Symposium Digest (Cat. No.02CH37278), 2003
A new directivity-enhancement method for a microstrip directional coupler is presented. The method utilizes feedback elements between the collinear ports of the parallel-line coupler to generate an isolation zero at the desired frequency. The closed-form equations for designing such compensating elements are developed.

Robot visual servoing by direct image feedback

1999 European Control Conference (ECC), 1999
This paper analyzes the robot hand-eye coordination from the view point of integration of vision and control. A new scheme of direct image feedback control is proposed. It compares the real time sampled image with the desired one and forms an error image.

The Direct Synthesis of Compensators for Nonlinear Feedback Systems

IFAC Proceedings Volumes, 1983
Abstract A computer method is devised for the direct time domain synthesis of linear compensators for feedback systems containing a single, bounded nonlinearity. A linear equivalent gain is first defined to represent the nonlinearity over a specified range of input signals and the nonlinear error function so generated is used to impose bounds on the ...

Feedback-directed thread scheduling with memory considerations

Proceedings of the 16th international symposium on High performance distributed computing, 2007
This paper describes a novel approach to generate an optimized schedule to run threads on distributed shared memory (DSM) systems. The approach relies upon a binary instrumentation tool to automatically acquire the memory sharingrelationship between user-level threads by analyzing their memory trace.
