Your question is still unclear. You can use glpk in two ways. The first way is to use glpsol, the stand-alone lp/mip solver. In this case you should provide problem data either in mps or cplex format or write your model in the glpk modeling language and then run glpsol from the command line to solve your problem. The second way is to use glpk api that assumes programming in C or C++. You can find an example C program in the glpk reference manual included in the package distribution. For more details please see the reference manual. _______________________________________________ Help-glpk mailing list Help-glpk@... http://lists.gnu.org/mailman/listinfo/help-glpk
	Re: R: Re: how show iterations? by Humberto César Brandão de Oliveira :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message I use GLPK with C. But I need show all iterations.
