% The column and nonzero counts in the PROBLEM SUMMARY TABLE below exclude  
% slack and surplus columns and the right-hand side vector, but include     
% the cost row.  We have omitted other free rows and all but the first      
% right-hand side vector, as noted below.  The byte count is for the        
% MPS compressed file; it includes a newline character at the end of each   
% line.  These files start with a blank initial line intended to prevent    
% mail programs from discarding any of the data.  The BR column indicates   
% whether a problem has bounds or ranges:  B stands for "has bounds", R     
% for "has ranges".  The BOUND-TYPE TABLE below shows the bound types       
% present in those problems that have bounds.                               
%                                                                           
% The optimal value is from MINOS version 5.3 (of Sept. 1988)

% STANDGUB includes GUB markers; with these lines removed (lines in         
% the expanded MPS file that contain primes, i.e., that mention the rows    
% 'EGROUP' and 'ENDX'), STANDGUB becomes the same as problem STANDATA;      
% MINOS does not understand the GUB markers, so we cannot report an         
% optimal value from MINOS for STANDGUB.  STANDMPS amounts to STANDGUB      
% with the GUB constraints as explicit constraints.
