This delay is entirely my own fault. In fact, I have to thank the many contributors to this report even more than usually: never before did I have to ask and push so little; several entries (and quite a few new entries) landed in my inbox before or on the deadline. Thank you very much! As most of you have probably be waiting for the Report a long time already and are eager to get ahead to the actual contents, let me just enumerate a few technical points: ◦ I am trying to be more strict about the rule that entries that have not been changed twice are removed. If something is removed, it doesn’t mean that is does not exist anymore. But on the other hand, I prefer no content over outdated content, so if in doubt, I remove. All of you who would like to see you entry included again, just submit an entry for the next report! ◦ As in the previous editions, I’ve marked entries that have not been in the previous report in blue (or gray, if viewed without color). Entries that have had (at least small) updates have a blue header. ◦ I have removed the “Haskell events” section. I lack time to keep it up-to-date, and I haven’t received any entries from others. I would appreciate if someone would be willing to sub-edit the events section for the next report. Just drop me a mail. ◦ The next report (the tenth!) will appear in May 2006, so please, already mark the last weeks of April, because the new entries will be due by then. As always, feedback is very welcome [email protected]. Now, I wish you pleasant reading!

  • A Type and Scope Safe Universe of Syntaxes with Binding: Their Semantics and Proofs
    ZU064-05-FPR jfp19 26 March 2020 16:6 Under consideration for publication in J. Functional Programming 1 A Type and Scope Safe Universe of Syntaxes with Binding: Their Semantics and Proofs GUILLAUME ALLAIS, ROBERT ATKEY University of Strathclyde (UK) JAMES CHAPMAN Input Output HK Ltd. (HK) CONOR MCBRIDE University of Strathclyde (UK) JAMES MCKINNA University of Edinburgh (UK) Abstract Almost every programming language’s syntax includes a notion of binder and corresponding bound occurrences, along with the accompanying notions of α-equivalence, capture-avoiding substitution, typing contexts, runtime environments, and so on. In the past, implementing and reasoning about programming languages required careful handling to maintain the correct behaviour of bound variables. Modern programming languages include features that enable constraints like scope safety to be expressed in types. Nevertheless, the programmer is still forced to write the same boilerplate over again for each new implementation of a scope safe operation (e.g., renaming, substitution, desugaring, printing, etc.), and then again for correctness proofs. We present1 an expressive universe of syntaxes with binding and demonstrate how to (1) implement scope safe traversals once and for all by generic programming; and (2) how to derive properties of these traversals by generic proving. Our universe description, generic traversals and proofs, and our examples have all been formalised in Agda and are available in the accompanying material available online at https://github.com/gallais/generic-syntax. 1 Introduction In modern typed programming languages, programmers writing embedded DSLs (Hudak (1996)) and researchers formalising them can now use the host language’s type system to help them.

  • Domain-Specific Languages for Modeling and Simulation

Gutachter: Prof. Dr. Adelinde M. Uhrmacher (Universität Rostock) Prof. Rocco De Nicola (IMT Lucca) Prof. Hans Vangheluwe (Universität Antwerpen) Eingereicht am 14. September 2020 Verteidigt am 8. Januar 2021 Abstract Simulation models and simulation experiments are increasingly complex. One way to handle this complexity is developing software languages tailored to specifc application domains, so-called domain-specifc languages (DSLs). This thesis explores the potential of employing DSLs in modeling and simulation. We study diferent DSL design and implementation techniques and illustrate their benefts for expressing simulation models as well as simulation experiments with several examples. Regarding simulation models, we focus on discrete-event models based on continuous- time Markov chains (CTMCs). Most of our work revolves around ML-Rules, an rule-based modeling language for biochemical reaction networks. First, we relate the expressive power of ML-Rules to other currently available modeling languages for this application domain. Then we defne the abstract syntax and operational semantics for ML-Rules, mapping models to CTMCs in an unambiguous and precise way. Based on the formal defnitions, we present two approaches to implement ML-Rules as a DSL. The core of both implementations is fnding the matches for the patterns on the left side of ML-Rules’ rules.

  • Rule Base with Frequent Bit Pattern and Enhanced K-Medoid Algorithm for the Evaluation of Lossless Data Compression
    Volume 3, No. 1, Jan-Feb 2012 ISSN No. 0976-5697 International Journal of Advanced Research in Computer Science RESEARCH PAPER Available Online at www.ijarcs.info Rule Base with Frequent Bit Pattern and Enhanced k-Medoid Algorithm for the Evaluation of Lossless Data Compression. Nishad P.M.* Dr. N. Nalayini Ph.D Scholar, Department Of Computer Science Associate professor, Department of computer science NGM NGM College, Pollachi, India College Pollachi, Coimbatore, India [email protected] [email protected] Abstract: This paper presents a study of various lossless compression algorithms; to test the performance and the ability of compression of each algorithm based on ten different parameters. For evaluation the compression ratios of each algorithm on different parameters are processed. To classify the algorithms based on the compression ratio, rule base is constructed to mine with frequent bit pattern to analyze the variations in various compression algorithms. Also, enhanced K- Medoid clustering is used to cluster the various data compression algorithms based on various parameters. The cluster falls dissentingly high to low after the enhancement. The framed rule base consists of 1,048,576 rules, which is used to evaluate the compression algorithm. Two hundred and eleven Compression algorithms are used for this study. The experimental result shows only few algorithm satisfies the range “High” for more number of parameters. Keywords: Lossless compression, parameters, compression ratio, rule mining, frequent bit pattern, K–Medoid, clustering. I. INTRODUCTION the maximum shows the peek compression ratio of algorithms on various parameters, for example 19.43 is the Data compression is a method of encoding rules that minimum compression ratio and the 76.84 is the maximum allows substantial reduction in the total number of bits to compression ratio for the parameter EXE shown in table-1 store or transmit a file.

  • First-Class Type Classes
    First-Class Type Classes Matthieu Sozeau1 and Nicolas Oury2 1 Univ. Paris Sud, CNRS, Laboratoire LRI, UMR 8623, Orsay, F-91405 INRIA Saclay, ProVal, Parc Orsay Universit´e, F-91893 [email protected] 2 University of Nottingham [email protected] Abstract. Type Classes have met a large success in Haskell and Is- abelle, as a solution for sharing notations by overloading and for spec- ifying with abstract structures by quantification on contexts. However, both systems are limited by second-class implementations of these con- structs, and these limitations are only overcomed by ad-hoc extensions to the respective systems. We propose an embedding of type classes into a dependent type theory that is first-class and supports some of the most popular extensions right away. The implementation is correspond- ingly cheap, general and integrates well inside the system, as we have experimented in Coq. We show how it can be used to help structured programming and proving by way of examples. 1 Introduction Since its introduction in programming languages [1], overloading has met an important success and is one of the core features of object–oriented languages. Overloading allows to use a common name for different objects which are in- stances of the same type schema and to automatically select an instance given a particular type. In the functional programming community, overloading has mainly been introduced by way of type classes, making ad-hoc polymorphism less ad hoc [17]. A type class is a set of functions specified for a parametric type but defined only for some types.
