Hello Fabio, please, find appended an excerpt of doc/glpk.pdf of the source distribution, chapter 2.9.5.
Best regards Xypron Terminal output Solving a MIP problem may take a long time, so the solver reports some information about best known solutions, which is sent to the terminal. This information has the following format: +nnn: mip = xxx <rho> yyy gap (ppp; qqq) where: ‘nnn’ is the simplex iteration number; ‘xxx’ is a value of the objective function for the best known integer feasible solution (if no integer feasible solution has been found yet, ‘xxx’ is the text ‘not found yet’); ‘rho’ is the string ‘>=’ (in case of minimization) or ‘<=’ (in case of maximization); ‘yyy’ is a global bound for exact integer optimum (i.e. the exact integer optimum is always in the range from ‘xxx’ to ‘yyy’); ‘gap’ is the relative mip gap, in percents, computed as gap = |xxx − yyy|/(|xxx| + DBL EPSILON) · 100% (if gap is greater than 999.9%, it is not printed); ‘ppp’ is the number of subproblems in the active list, ‘qqq’ is the number of subproblems which have been already fathomed and therefore removed from the branch-andbound search tree. -------- Original-Nachricht -------- > Datum: Tue, 25 May 2010 18:51:34 -0300 > Betreff: [Help-glpk] Out in the prompt > Hi! > > What means "+ 31229" and "(70; 68)" in "+ 31229: mip = not found > yet > >= 0.000000000e+000 (70; 68) " ? > > Because I execute a problem in glpsol and this is the out in the prompt, > but > I don't understand. > > Thanks, > > Fabio Araujo. -- GRATIS für alle GMX-Mitglieder: Die maxdome Movie-FLAT!
