[Help-glpk] Changes in solution file format?

[Mike Steglich]

Hi,

I'm wondering whether there is an undocumented change in the solution plain 
text format. 

Solving a problem with glpsol v. 4.52 with 7 constraints and 12 variables the 
first line in the solution file (generated with --write) is "8 12". I 
understand it as 8 lines (objective function + 7 constraints) and 12 variables. 
Doing the same thing with glpsol v. 4.53 a first line "7 12" (7 constraints and 
12 variables) occurs.  

In the manual is the behavior of glpsol v.4.52 described (page 86) :
m n 
m is the number of rows (auxiliary variables);
n is the number of columns (structural variables);


Am I right or wrong?


Thanks,

Mike
