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. If 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.

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.
