1. Classification of LOLA example files

The names of the LOLA example files are constructed the following way:

name_description.extension

where "name" usually is a general description of the information given in the file.
"Description" is a more detailled description. This part is optional and not given for every file. It is used to characterize files including information for gauges (_gauge.) or with more then one criteria (_bicrit.) where both cases could arise together (_bicrit_gauge.). Furtheron restriction files use this description to explain the type of the restriction (e.g. _circle. for a file containing a circle as restriction) The general type of the example file can be identified by its "extension":

*.loc a file containing information about locations in the plane (see LOLA

manual section 4.1);
*.dis a file containing information about demand and supply locations in case

of discrete problems;
*.gra a file containing information about a network of locations (see LOLA

manual section 4.5);

*.gau a file containing a list of polyhedral gauges (see LOLA manual section

4.4);

*.mat a file containing an interaction matrix for N-facility problems in the

plane (see LOLA manual section 4.2);

*.res a file containing restrictions in form of forbidden regions (see LOLA

manual section 4.3);
*.bar a file containing restrictions in form of barriers;
