The testprob collection[edit]

Introduction[edit]

Each of the sections in this part will demonstrate a problem class. Most sections also have a small example in Matlab code with a formal mathematical problem description.

The functions probInit and tomrun respectively initializes and solves the problems in Matlab. For example:

Prob = probInit('gp_prob',1);
tomRun('',Prob)

Problems[edit]

The modellib collection[edit]

Introduction[edit]

The bundle modellib is a collection of linear and mixed-integer programming problems. For each problem there are two m-files. One that formulate and define the problem with words and tables, and a second that interpret the tables into the standard TOMLAB prob format and solves it. In order to interpret the results a large amount of text is displayed explaining the x_k vector.

The problems in modellib are originally from a translation by Hickpe of the text "Programmation linare" by Gueret, Prins and Seveaux with the english title "Applications of optimization...".

Problems[edit]

Additional downloads: lp prob, milp prob and qp prob[edit]

At the TOMLAB downloads page three zip files with more problems can be found. Many of these are quite large and may be good as test cases for benchmarking. A package of about 250 MB with mixed LP/MILP are also available from your TOMLAB representative.
