Legenda
Columns in the table below are to be read as following:
Nr. ID of the benchmark. The prefixes N resp. O denote a newly added resp. a 2011 benchmark. New problems with a * denote an old problem with changes in its specification.
Author(s). Names of authors. A ^{*} denotes that they authored the respective package in previous years.
Type. One of Search, Optimization, Query. See the problem classification page.
Complexity. One of P, NP or Beyond-NP. To be read as the known complexity of the underlying decisional problem associated to the domain at hand. P: known to be solvable in polynomial time in the size of input. NP: known to be solvable
in non-deterministic polynomial time in the size of input. Beyond-NP: any other problem.
Domain. The domain type, e.g. graph, scheduling, planning etc.
Problem Description. Problem specifications in their official form, with latest notes and updates.
Sample Instances. A link to sample instances for the given problem.
Checker. A checker script for validating solutions. See here for the checker I/O specifications.
ASP-Core-2 encoding. The encoding which will be used in the System Track. Recall that the Model & Solve track has no fixed encoding, no fixed input language instead.
Instance set
The .zip file containing the sha256sums of all the instance family from which instances will be selected randomly is available here. The sha256sum of the file itself is this. Note, the archive is password protected, credentials to be disclosed after the competition.
How we will select instances is specified here.
Full instance set: here
Alternative Encodings
In the System Track, participants can propose strictly syntactical variants of official encodings:
Alternative encodings compatible with Gringo 3: download
Alternative encodings compatible with WASP: download
What do checkers expect as their input? How do I check my solution compliance ?

Changelog
Apr 11th, 2013 The numbers chosen as starting seed are 15-35-38-44-48, as of the Euromillion Lottery of Tuesday April 9th 2013.
