Download LINLib (LP, MIP and QCP)

The purpose of this collection is to provide users with an established and varied set of both theoretical and practical LP, MIP and QCP test models. Users can download the complete library of models, or download models by origin (for example, NEOS, MIPLIB, NETLIB) or by model size. The model size classification is in terms of number of nonzeros.

When downloading by size or by origin, users must download model and best known point data seperately.

Read more about the LP, MIP, and QCP models in each grouping in the size description

Model zip archives contain:
- all LP, MIP, and QCP models of that size (.gms file)
- all LP, MIP, and QCP model data of that size (.gdx file)

Point zip archives contain:
- best known point of models of that size (.gdx file)

The size classification is as follows:

  tiny   : number of nonzeros between      0  and    2000
  small  : number of nonzeros between   2000  and   50000
  medium : number of nonzeros between  50000  and  200000
  large  : number of nonzeros between 200000  and 1000000
  huge   : number of nonzeros greater        than 1000000
