DLV-Complex: The Project

DLV-Complex is an Answer Set Programming System extending [http://www.dlvsystem.com DLV] by means of functions. It is a very powerful ASP system supporting (recursive) functions, sets, and lists, along with libraries for their manipulations.

DLV-Complex is based on the [http://www.dlvsystem.com DLV] system and on the [http://www.mat.unical.it/ianni/wiki/dlvex DLV-EX] framework, from which it inherits the possibility of defining external predicates. You will find everything you need in order to create your own external predicates collected in libraries on the [http://www.mat.unical.it/ianni/wiki/dlvex DLV-EX] page.

The Team

[#TOC Top of Page]



DLV-Complex is actively developed. To receive notifications about new releases and other important events regarding DLV-Complex, just have a look at this page, or drop us a note [mailto:calimeri{NOSPAM-at-NOSPAM}mat.unical.it here].

Please always use the most current version of DLV-Complex (cf. [#history version history]).


Latest Version


Standard Version

We currently provide a command-line version in binary form for Linux, Windows 95/98/NT/2000/XP/Vista and Mac OS.

  • Download latest [attachment:dl-complex.linux.20100303.beta linux version] (requires libstdc++6.0.10 or greater)
  • Download latest [attachment:dl-complex.win.20100303.beta.exe windows version]
  • Download latest [attachment:dl-complex.mac.20100303.beta macOS version]


Static Version

attachment:new.gif We offer also a statically linked executable (currently only linux and windows versions), that includes list and set manipulation libraries. This version do not need any pre-installed dynamic library on your system; in addition, it is self-contained, meaning that you do not need to download any library (such as those below) in order to enjoy full lists and set support. It is ready-to-use. :) Nevertheless, this version do not support external predicates/libraries (see [http://www.mat.unical.it/ianni/wiki/dlvex DLV-EX] page).

  • Download latest [attachment:dl-complex.linux.20100303.static.beta linux STATIC version]
  • Download latest [attachment:dl-complex.win.20100303.static.beta.exe windows STATIC version]


Latest Libraries

  • List-And-Set library is needed in order to exploit built-in manipulation functions/predicates for list and set terms, unless you use a [#staticVersion static version] of DLV-Complex.
    • Download latest [attachment:ListAndSet.20100303.so linux version] (.so)

    • Download latest [attachment:ListAndSet.20100303.dll windows version] (.dll)

    • Download latest [attachment:ListAndSet.20100303.macOS.so macOS version] (.so)

  • Other external predicate libraries can be found on the [http://www.mat.unical.it/ianni/wiki/dlvex DLV-EX] page.


Developing New External Predicates and Libraries

If will find everything you need in order to create your own external predicates (collected in dynamic libraries) on the [http://www.mat.unical.it/ianni/wiki/dlvex DLV-EX] page.

Documentation & Examples

We provide here a quick reference guide, a short tutorial and some examples.

Documentation and examples will be updated accordingly to the evolution of the system, so check them out periodically. For a full documentation on [http://www.dlvsystem.com DLV] please visit the official [http://www.dlvsystem.com web page]. You might also find useful to check the official [http://www.mat.unical.it/ianni/wiki/dlvex web page] of [http://www.mat.unical.it/ianni/wiki/dlvex DLV-EX] out for docs and info.
