Overview

There will be some scripts to generate important information, the last updated information files (so you don't have to run those scripts often), and a script or program to separate the problems you want.

So far:

• selectproblems.rb: Select problems using the options from options.rc, or the default options, or from the command line. The problems meeting the criteria are stored on the file problem.list.
• options.rc: Options for the selectproblems.rb script. If this file is erased, a default can be generated running the script.
• problem.list: Output from the script selectproblems.rb. Originally, this file does not exits.
• getcodeinfo/getcodeinfo.sh: Generates the file sif.dcd using the CUTEst interface in getcodeinfo/.
• sif.dcd: File with the same problems from sif.bsc, and information generated from the CUTEst interface. All information is as declared in the .SIF files, therefore hhe number of variables and constraints are identified as a number, i.e., not variable.
• getsiflist.rb: Retrieves from site [1] the list of problems with information and generates the file sif.bsc
• sif.bsc: File with all problems in the site, the number of variables, constraints, type of function, type of constraints, and some other informations. Check [2] for complete relation. This file is formatted for easier reading/parsing. No information from this file is being used now
• README.md: This file.
• LICENSE: License file

Installing and Running

The default use will be to select the problems. Edit the file options.rc and run

$ ./selectproblems.rb

The problem list will be the file problem.list.

If you want to override any option with the command line you can use

$ ./selectproblems.rb --<option> <value>

Where <option> must be a valid option. Run with --usage for list.

Generate (or update) sif.bsc with

$ ./gensiflist.rb

Generate (or update) sif.dcd with

$ cd getcodedinfo
$ ./getcodedinfo.sh

WARNING: Generating sif.dcd requires a working installation of CUTEst and will take a reasonable amount of time.
