Sorry about that; I 'resolved' my problem. Guess the dust on this project was a bit thicker than I thought.Hope this is clear, but I thick the 'mip' solution file format of GLPK is the one stated below.
Note that the #rows (m) is increased by one, and the objective value is stated once more between the rows and the columns. Not sure why though... Timon
GLPK SOLUTION FILE FORMAT: * The file created by the routine glp_write_sol is a plain text file, * which contains the following information: * * m+1 n * stat obj_val * r_val[1] * . . . * r_val[m]
> * obj_val
* c_val[1] * . . . * c_val[n] * * where: * m is the number of rows (auxiliary variables); * n is the number of columns (structural variables); * stat is the solution status (GLP_UNDEF = 1, GLP_FEAS = 2, * GLP_NOFEAS = 4, or GLP_OPT = 5); * obj_val is the objective value; * r_val[i], i = 1,...,m, is the value of ith row; * c_val[j], j = 1,...,n, is the value of jth column. */
