% In the following, IIS stands for Irreducible Infeasible Subsystem, a set    
% of constraints which is itself infeasible, but becomes feasible when any    
% one member is removed.  Isolating an IIS from within the larger set of      
% constraints defining the model is one analysis approach.

% FOREST6, WOODINFE:  very small problems derived from network-based          
% forestry models.  The IIS in FOREST6 includes most of the rows.             
% WOODINFE is the example problem discussed in detail in Greenberg [1993],
