Automated and Algorithmic Debugging by Peter A. Fritzson Pdf
Debugging has always been a costly part of software development, and many attempts have been made to provide automatic computer support for this task.Automated debugging has seen major develoments over the last decade. Onesuccessful development is algorithmic debugging, which originated in logic programming but was later generalized to concurrent, imperative, and lazy functional languages. Important advances have also been made in knowledge-based program debugging, and in approaches to automated debugging based on static and dynamic program slicing based on dataflow and dependence analysis technology. This is the first collected volume of papers on automated debugging and presents latest developments, tutorial papers, and surveys.
Generalized Algorithmic Debugging by N. Shahmehri Pdf
Abstract: "This thesis presents a novel method for semi-automatic program debugging -- the Generalized Algorithmic Debugging Technique, GADT. The notion of declarative algorithmic debugging was first introduced for logic programming. However, this is the first algorithmic debugging method based on the principle of declarative debugging which can handle the debugging of programs written in an imperative language including loops and side-effects. In order to localize a bug, the debugging algorithm incrementally acquires knowledge about the debugged program. The knowledge is supplied by the user. The algorithm terminates when the bug has been localized to within the body of a procedure or an explicit loop. The generalized algorithmic debugging method uses program transformation and program flow analysis techniques to transform the subject program to a largely side-effect-free internal form which is used for bug localization. Thus, this algorithm defines two views of a program: (1) The user view which is the original program with side-effects and (2) the transformed view which is the transformed side-effect-free version of the original program. Transparent program debugging is supported by maintaining a mapping between these two views. The bug localization algorithm works on the transformed version, whereas user interactions are defined in terms of the user view. We have presented a general technique which it [sic] is not based on any ad-hoc assumptions about the subject program. The flexibility of this method has made it possible to further improve the bug localization algorithm by employing a number of other techniques, i.e. program slicing and test database lookup, thus increasing the degree of automation provided by GADT. These extensions are topics for ongoing research projects and future work. A survey and evaluation of a number of automated debugging systems and the techniques behind these systems are also presented. We have introduced several criteria for comparing these techniques with GADT. A prototype implementation of the generalized algorithmic debugging technique has been carried out to verify its feasibility, and to provide feedback for further refinement of the method. This has already resulted in a more efficient set of transformations, described in the thesis, compared to the initial prototype."
Using Assertions in Declarative and Operational Models for Automated Debugging by Linkoeping University. Dept. of Computer and Information Science,Peter Fritzson,Mikhail Auguston,Nahid Shahmehri Pdf
Abstract: "The paper presents an improved method for semi- automatic bug localization, by extending the Generalized Algorithmic Debugging Technique, GADT [Fritzson, et.al-91], which uses declarative assertions about program units such as procedures, with operational assertions about program behavior. For example, functional properties are best expressed through declarative assertions about procedure units, whereas order-dependent properties such as race conditions in parallel processing, or sequencing constraints in general, are more easily expressed using operational semantics. A powerful assertion language, called FORMAN, has been developed to this end. Such assertions can be collected into assertion-libraries, which can greatly increase the degree of automation in bug localization. The long-range goal of this work is a semi-automatic debugging and testing system which can be used during large- scale program development of non-trivial programs. The need for such automated debugging support will increase as applications on parallel architectures become more prevalent, since such programs are both harder to write and to debug, partly because of non-sequential execution semantics. Our previously developed GADT method was the first declarative algorithmic debugging technique for procedural imperative languages with side-effects. GADT is generally applicable to procedural languages, and is not dependent on any ad hoc assumptions regarding the subject program. The original form of algorithmic debugging, introduced by Shapiro [Shapiro-82], is however limited to small Prolog programs without side-effects. Another drawback of the original method is the large number of interactions with the user during bug localization. To our knowledge, the extended GADT presented here is the first method which uses powerful operational assertions in algorithmic debugging. In addition to providing support for local-level bug localization within procedures (which is not handled well by basic algorithmic debugging), the operational assertions reduce the number of irrelevant questions to the programmer during bug localization, thus further improving bug localization. Previously, we have enhanced the bug localization properties of GADT, using lookup in a category partition testing database. In addition, we use program slicing, a data flow analysis technique, to dynamically compute which parts of the program are relevant for the search. A prototype of the GADT has been implemented in Pascal, supporting debugging in a subset of Pascal. An interpreter of FORMAN assertions has also been implemented in Pascal. During bug localization, both types of assertions are evaluated on execution traces."

Debug Automation from Pre-Silicon to Post-Silicon by Mehdi Dehbashi,Görschwin Fey Pdf
This book describes automated debugging approaches for the bugs and the faults which appear in different abstraction levels of a hardware system. The authors employ a transaction-based debug approach to systems at the transaction-level, asserting the correct relation of transactions. The automated debug approach for design bugs finds the potential fault candidates at RTL and gate-level of a circuit. Debug techniques for logic bugs and synchronization bugs are demonstrated, enabling readers to localize the most difficult bugs. Debug automation for electrical faults (delay faults)finds the potentially failing speedpaths in a circuit at gate-level. The various debug approaches described achieve high diagnosis accuracy and reduce the debugging time, shortening the IC development cycle and increasing the productivity of designers. Describes a unified framework for debug automation used at both pre-silicon and post-silicon stages; Provides approaches for debug automation of a hardware system at different levels of abstraction, i.e., chip, gate-level, RTL and transaction level; Includes techniques for debug automation of design bugs and electrical faults, as well as an infrastructure to debug NoC-based multiprocessor SoCs.

ETAPS 2004 was the seventh instance of the European Joint Conferences on Theory and Practice of Software. ETAPS is an annual federated conference that was established in 1998 by combining a number of existing and new conferences. This year it comprised ?ve conferences (FOSSACS, FASE, ESOP, CC, TACAS), 23 satellite workshops, 1 tutorial, and 7 invited lectures (not including those that are speci?c to the satellite events). The events that comprise ETAPS address various aspects of the system - velopment process, including speci?cation, design, implementation, analysis and improvement. The languages, methodologies and tools that support these act- ities are all well within its scope. Di?erent blends of theory and practice are r- resented, with an inclination towards theory with a practical motivation on the one hand and soundly based practice on the other. Many of the issues involved in software design apply to systems in general, including hardware systems, and theemphasisonsoftwareisnotintendedtobeexclusive.
Multi-Agent Programming: by Rafael H. Bordini,Mehdi Dastani,Jürgen Dix,Amal El Fallah Seghrouchni Pdf
Multi-Agent Systems are a promising technology to develop the next generation open distributed complex software systems. The main focus of the research community has been on the development of concepts (concerning both mental and social attitudes), architectures, techniques, and general approaches to the analysis and specification of multi-agent systems. This contribution has been fragmented, without any clear way of “putting it all together”, rendering it inaccessible to students and young researchers, non-experts, and practitioners. Successful multi-agent systems development is guaranteed only if we can bridge the gap from analysis and design to effective implementation. Multi-Agent Programming: Languages, Tools and Applications presents a number of mature and influential multi-agent programming languages, platforms, development tools and methodologies, and realistic applications, summarizing the state of the art in an accessible manner for professionals and computer science students at all levels.
Algorithm Engineering by Matthias Müller-Hannemann,Stefan Schirra Pdf
Algorithms are essential building blocks of computer applications. However, advancements in computer hardware, which render traditional computer models more and more unrealistic, and an ever increasing demand for efficient solution to actual real world problems have led to a rising gap between classical algorithm theory and algorithmics in practice. The emerging discipline of Algorithm Engineering aims at bridging this gap. Driven by concrete applications, Algorithm Engineering complements theory by the benefits of experimentation and puts equal emphasis on all aspects arising during a cyclic solution process ranging from realistic modeling, design, analysis, robust and efficient implementations to careful experiments. This tutorial - outcome of a GI-Dagstuhl Seminar held in Dagstuhl Castle in September 2006 - covers the essential aspects of this process in ten chapters on basic ideas, modeling and design issues, analysis of algorithms, realistic computer models, implementation aspects and algorithmic software libraries, selected case studies, as well as challenges in Algorithm Engineering. Both researchers and practitioners in the field will find it useful as a state-of-the-art survey.
