1. Defect patterns and software metric correlations in a mature ubiquitous system

Subjects
Computer Science - Software Engineering
Abstract

Software engineering is not an empirically based discipline. Consequently, many of its practices are based on little more than a generally agreed feeling that something may be true. Part of the problem is that it is both relatively young and unusually rich in new and often competing methodologies. As a result, there is little time to infer important empirical patterns of behaviour before the technology moves on. Very occasionally an opportunity arises to study the defect growth and patterns in a well-specified software system which is also well-documented and heavily-used over a very long period. Here we analyse the defect growth and structural patterns in just such a system, a numerical library written in Fortran evolving over a period of 30 years. This is important to the wider community for two reasons. First, the results cast significant doubt on widely-held long standing language-independent beliefs and second, some of these beliefs are perpetuated in modern technologies. It therefore makes good sense to use empirical long-term data as it becomes available to re-calibrate those generalisations. Finally, we analyse the phenomenon of defect clustering providing further empirical support for its existence., Comment: 13 pages, 6 figures, 2 tables, 30 references

17. THINKING BEYOND THE HUMAN: DESIGN APPROACHES FOR ROBOTS AND AI IN OPERA.

Author

FICARRA, EVELYN, HOPKINS, TIM, JOCHUM, ELIZABETH, and KIEFER, CHRIS

Abstract

Opera has historically been a site for developing new and emerging technologies. More recently, opera has proven a rich environment for investigating future scenarios involving human-robot interaction and exploring the potential of robot performers. The explosion of enthusiasm for AI and the ubiquity of machine learning tools have created numerous possibilities for generating creative content in music, poetry, images, and choreography. This article outlines efforts to explore the creative possibilities of robots and AI through a dedicated workshop with researchers from diverse fields. Our goal is to begin thinking beyond the human to investigate what robot performers might look and behave like when designed from a relational rather than a representational approach. We provide a brief history of robots on stage, including the authors' prior work developing original performances featuring robots and human performers. We describe our iterative design approach and lowfi prototypes, summarizing key insights from the workshop. Finally, we analyze the workshop outcomes and consider the trade-offs of working with existing robots and the possibilities for working with open, configurable systems. [ABSTRACT FROM AUTHOR]

19. Algorithm 830: another visit with standard and modified givens transformations and a remark on algorithm 539

Author

Hanson, Richard J. and Hopkins, Tim

Subjects
Algorithm, Algorithms -- Research
Abstract

First we report on a correction and improvement to the Level 1 BLAS routine srotmg for computing the Modified Givens Transformation (MG). We then, in the light of the performance of the code on modern compiler/hardware combinations, reconsider the strategy of supplying separate routines to compute and apply the transformation. Finally, we show that the apparent savings in multiplies obtained by using MG rather than the Standard Givens Transformation (SG) do not always translate into reductions in execution time.

Abstract

We report on a number of coding problems that occur frequently in published CALGO software and are still appearing in new algorithm submissions. Using Algorithm 639 as an extended example, we describe how these types of faults may be almost entirely eliminated using available commercial compilers and software tools. We consider the levels of testing required to instil confidence that code performs reliably. Finally, we look at how the source code may be re-engineered, and thus made more maintainable, by taking account of advances in hardware and language development.

Abstract

Since 1960 the Association for Computing Machinery has published a series of refereed algorithm implementations known as the Collected Algorithms of the ACM (CALGO). Most of those published since 1975 are mathematical algorithms, and many of them remain useful today. In this paper we describe measures that have been taken to bring some 300 of these latter codes to an up-to-date and consistent state. Categories and Subject Descriptors: G.4 [Mathematical Software]:--Certification and testing; Reliability and robustness; D.2.7 [Software Engineering]: Distribution, Maintenance, and Enhancement--Portability; Restructuring, reverse engineering, and reengineering General Terms: Algorithms Additional Key Words and Phrases: Standardization, software reengineering, software tools, software testing

28. An analytical approach: Explicit inverses of periodic tridiagonal matrices

Author

Hopkins, Tim, Kılıç, Emrah, Hopkins, Tim, and Kılıç, Emrah

Abstract

We derive an explicit formula for the inverse of a general, periodic, tridiagonal matrix. Our approach is to derive its LU factorization using backward continued fractions (BCF) which are an essential tool in number theory. We then use these formulae to construct an algorithm for inverting a general, periodic, tridiagonal matrix which we implement in Maple.1 Finally, we present the results of testing the efficiency of our new algorithm against another published implementation and against the library procedures available within Maple to invert a general matrix and to compute its determinant.

Abstract

The Collected Algorithms of the ACM (CALGO) is now the longest running journal-published series of algorithms. After placing CALGO in the context of other journal algorithm series, we discuss the factors that we believe have made CALGO the well respected means of publishing mathematical software that it is today. We report on how moving with the times and technology has ensured the survival of CALGO, and we look briefly at how we may continue this in the near future.

45. Defect patterns and structural properties in a mature well-specified software system

Hopkins, Tim and Hatton, Leslie

Abstract

Software engineering is not an empirically based discipline. As a result, many of its practices are based on little more than a generally agreed feeling that something may be true. Part of the problem is that it is both relatively young and unusually rich in new and often competing methodologies. As a result, there is little time to infer important empirical patterns of behaviour before the technology moves on. Very occasionally an opportunity arises to study the defect growth and patterns in a well-specified software system which is also well-documented and heavily-used over a long period. Here we analyse the defect growth and structural patterns in just such a system, a numerical library written in Fortran evolving over a period of 30 years. This is important to the wider community for two reasons. First, the results cast significant doubt on widely-held long standing beliefs and second, some of these beliefs are perpetuated in more modern technologies. Since we obviously generalise from older languages to new, it makes good sense to use empirical long-term data when it becomes available to re-calibrate those generalisations. At the same time, the results contain intriguing glimpses into defect behaviour which may transcend whatever technology is in use.

Abstract

We propose a set of new Fortran reference implementations, based on an algorithm proposed by Kahan, for the Level 1 BLAS routines *NRM2 that compute the Euclidean norm of a real or complex input vector. The principal advantage of these routines over the current offerings is that, rather than losing accuracy as the length of the vector increases, they generate results that are accurate to almost machine precision for vectors of length N < Nmax where Nmax depends upon the precision of the floating point arithmetic being used. In addition, we make use of intrinsic modules, introduced in the latest Fortran standards, to detect occurrences of non-finite numbers in the input data and return suitable values as well as setting IEEE floating point status flags as appropriate. A set of C interface routines is also provided to allow simple, portable access to the new routines. To improve execution speed, we advocate a hybrid algorithm; a simple loop is used first and, only if IEEE floating point exception flags signal, do we fall back on Kahan’s algorithm. Since most input vectors are “easy,” i.e., they do not require the sophistication of Kahan’s algorithm, the simple loop improves performance while the use of compensated summation ensures high accuracy. We also report on a comprehensive suite of test problems that has been developed to test both our new implementation and existing codes for both accuracy and the appropriate settings of the IEEE arithmetic status flags.

Abstract

A numerical procedure to approximate certain kinds of stochastic differential equations with time-delay is described. First, it is shown how a deterministic population model with continuously distributed time-delay can be transformed into a stochastic population model. A numerical method to solve the stochastic equations is described. An error analysis of the method is given. The numerical method is then applied to obtain approximations for four different systems of stochastic differential equations with time-delay, including three biological systems.
