Requires Python 3.3+, (Python 3.4+ on windows)

To build a local copy of csplib to view locally type:

make        # Builds CSPLib to the _deploy directory
make serve  # Starts a local web server to view the files
<open localhost:8000 in your browser>

To add a new problem use new_problem.sh to create a basic outline.

Problem Specification

Each problem is stored in the Problems directory. The best way to get a feeling for how a problem is stored is to look at an existing problem (Problem/prob001 is a good start).

Each problem is built from the following parts:

specification.md - The basic description of the problem. This will contain a title, proposer, category, and an English description of the problem. This is technically all that is required.
references - This directory contains the references, usually in references.bib file as bibtex.
models, data and results - The models, data and results directories store models of the problem, data files and any known results. The exact structure of these is described below.

The assets/ directory will be copied but not automatically linked to. Use this directory for files, such as images, which are linked to from specification.md

specification.md

The specification needs to start with a Title, Proposer and Category in the following format:

---
Title:    Magic Hexagon
Proposer: Toby Walsh
Category:
    - Design and configuration
    - Combinatorial mathematics
    - Games and puzzles
---

If the Proposer or Category have multiple values, they are put on a new line as shown above.

The rest of the specification is written in markdown. References from the references section can be cited using the notation cite{bibref}.

References

References are stored in the references directory. The file references.bib should contain references in standard BibTeX format. Any text in the file notes.inline.md will be listed at the top of the references page.

A problem can be referenced using its id, [prob058] will be shown hyperlinked as [prob058]. {prob058} will shown hyperlinked as Discrete Lot Sizing Problem

Languages can also be referenced e.g. [Minion]

Models, data and results directories

Each of these directories are handled in the same way.

Files can be added to these directories by simply placing the file in the appropriate directory. Human readable files are displayed in place, binary files are given a download link. If any file is incorrectly identified as binary or human readable, please submit a bug report!

You can describe a file file.txt in a file file.txt.metadata. This can contain a Title, and a Type. The file should be formatted as follows:

---
Title: This describes the data file
Type: The type
---

In general, Type is only useful for models and data.

You can also use files with the extension .inline.md which will be displayed inline directly in the results/references/model tab. See problem prob013 for an example of all these types of files.

Language Specification

Languages are stored in the Languages directory. Languages do not store the models, data and results, these are stored with the problems and linked from the languages.

specification.md for Languages

The specification of languages is similar to problems, with a simpler design. Languages should contain a title, and (single or list of) extensions:

---
Title: MiniZinc
Extensions:
    - mzn
    - minizinc
---

The extensions will be matched against the file extensions, or Type contained in all models, data and results of all problems.
