Is there a 'not' predicate for ciao?
by Yacao Wang 20 Oct '05

20 Oct '05

Hi, I'm new to Prolog, I wonder if there is a 'not/1' or something similar to use in Ciao, or do I have to write it myself?

Hi, is there anyway to do that? I've tried hard to find this out but it seems that it can't be done. Is that true? ============================================================================== Message: Address: Action: help majordomo(a)clip.dia.fi.upm.es Info. on useful commands subscribe ciao-users-request(a)clip.dia.fi.upm.es Subscribe to this list unsubscribe ciao-users-request(a)clip.dia.fi.upm.es Unsubscribe from this list <whatever> ciao-users(a)clip.dia.fi.upm.es Send message to list ----------------------------------------------------------------------------- Archived messages: http://www.clip.dia.fi.upm.es/Mail/ciao-users/ -----------------------------------------------------------------------------

modifyng asserted clauses
by Alberto G. Corona 24 Aug '05

24 Aug '05

Tanks Bart. So I can create new predicates . I don´t touch prolog since the times of my Sinclair Spectrum. By the way, The Ciao-emacs integration is wonderful. I´m involved in a meta-programming project in which I need also to modify already asserted predicates . Can I get the definition of a clause and manage his body either as a list or as any other serial object that Ciao may have or, else, I must keep a copy of the asserted clause definitions in variables?

Ciao Prolog examples and tutorial?

Hi, I wonder where I can find some sample programs in Ciao Prolog (besides the ones in the 'example' folder), and detailed tutorials(besides the one on the homepage).

I couldn't find the details on the website anywhere.

Sounds very promising! If you need an extra beta-tester for this functionality at any stage, I would be happy to try it out on some of the applications I have in mind.

Special Semester on Groebner Bases and Related Methods 2006
by Alexander Zapletal 16 Aug '05

16 Aug '05

[ Please apologize for multiple postings ] I would like to invite you and your students to participate in the Special Semester on Gröbner Bases and Related Methods 2006, February July 2006 Linz and Hagenberg, Austria The special semester on Gröbner bases aims at bringing together researchers from all over the world for joint research on Gröbner bases and related theories and methods. Also, through the special semester, knowledge on these theories should be made available and disseminated in a new way that uses both recent advances in formalized mathematics as well as web technol-ogy. Part of the effort during the special semester will also go into special lectures, tutorials, and training and, after the special semester, events for the dissemination of the research re-sults will be organized. Both established researchers as well as junior researchers, postdocs, and PhD students are welcome to participate in the activities of the special semester. For details and application, see: http://www.ricam.oeaw.ac.at/srs/groeb/ A low resolution version of our poster is attached. You can download the high resolution version from our webpage. Yours sincerely, Bruno Buchberger (Chair) ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Alexander Zapletal, Dipl.-Ing.

Teams or equivalent?
by Ryan Kelly 16 Aug '05

16 Aug '05

Hi, I am interested in trying out the "Teams" functionality described in the paper "Implementing Distributed Concurrent Constraint Execution in the CIAO System", whereby distributed processes cooperate in the execution of a goal: http://clip.dia.fi.upm.es/papers/ciao-dis-impl-prode_bitmap.pdf I've found the concurrency primitives such as &> and <& in the library module "hlc", but I cannot find how to access predicates such as add_worker(Host,Id) which control the available workers. Has this functionality changed form since the above paper was produced, or am I simply not looking in the right place? As some background, I am a Masters student at the University of Melbourne, Australia, working on programming languages for multi-agent systems. Thanks for any help you can offer, Ryan ============================================================================== Message: Address: Action: help majordomo(a)clip.dia.fi.upm.es Info. on useful commands subscribe ciao-users-request(a)clip.dia.fi.upm.es Subscribe to this list unsubscribe ciao-users-request(a)clip.dia.fi.upm.es Unsubscribe from this list <whatever> ciao-users(a)clip.dia.fi.upm.es Send message to list ----------------------------------------------------------------------------- Archived messages: http://www.clip.dia.fi.upm.es/Mail/ciao-users/ -----------------------------------------------------------------------------

PADL 2006: Final Call For Papers
by Logic Programming Rsrch Association 16 Aug '05

16 Aug '05

----------------------------------------------------------------------------- CALL FOR PAPERS!!! Eighth International Symposium on Practical Aspects of Declarative Languages 2006 (PADL '06) http://www.cs.brown.edu/people/pvh/PADL06.html Charleston Place Hotel Charleston, South Carolina January 9-10 Co-located with ACM POPL'06 Declarative languages build on sound theoretical bases to provide attractive frameworks for application development. These languages have been successfully applied to vastly different real-world situations, ranging from data base management to active networks to software engineering to decision support systems. New developments in theory and implementation have opened up new application areas. At the same time, applications of declarative languages to novel problems raises numerous interesting research issues. Well-known questions include designing for scalability, language extensions for application deployment, and programming environments. Thus, applications drive the progress in the theory and implementation of declarative systems, and benefit from this progress as well. PADL is a forum for researchers and practioners to present original work emphasizing novel applications and implementation techniques for all forms of declarative concepts, including, functional, logic, constraints, etc. Topics of interest include: * innovative applications of declarative languages; * declarative domain-specific languages and applications; * practical applications of theoretical results; * new language developments & their impact on applications; * evaluation of implementation techniques on practical applications; * novel uses of declarative languages in the classroom; and * practical experiences PADL 06 welcomes new ideas and approaches pertaining to applications and implementation of declarative languages, and is not limited to the scope of the past five PADL symposia. PADL 06 will be co-located with the ACM POPL. IMPORTANT DATES AND SUBMISSION GUIDELINES Paper Submission: August 20, 2005 Notification: September 30, 2005 Final Manuscript: October 20, 2005 Symposium: January 9-10, 2005 Authors should submit an electronic copy of the full paper (written in English) in Postscript (Level 2) or PDF. Papers must be no longer than 15 pages, written in 11-point font and with single spacing. Since the final proceedings will be published as Lecture Notes in Computer Science by Springer Verlag, authors are strongly encouraged to use the LNCS paper formatting guidelines for their submission. Each submission must include on its first page the paper title; authors and their affiliations; contact author's email and postal addresses, telephone and fax numbers, abstract, and three to four keywords. The keywords will be used to assist us in selecting appropriate reviewers for the paper. If electronic submission is impossible, please contact the program chair for information on how to submit hard copies. MOST PRACTICAL PAPER AWARD The Most Practical Paper award will be given to the submission that is judged by the programm committee to be the best in terms of practicality, originality, and clarity of presentation. The program committee may choose not to make an award; or may make multiple awards.

Compilation on Linux/amd64?
by Ryan Kelly 03 Aug '05

03 Aug '05

Hi, I've had about a half-hour go at getting the latest Ciao release to compile on my Gentoo Linux system, with is running on an Athlon64 procressor (so the architecture is x86_64). According to ciao_get_arch this platform is not known to the installation procedure. I had some limited success getting the compile running, but there seem to be a few issues with the platform, such as the fact that sizeof(long) is not 4 which violates some assertions in the source code. I'm happy to work towards getting things compiling smoothly on this platform, but before I go hacking around too much I was wondering if anyone has already had success or any experience getting things working on such a platform?
