Hi All, I’m using GPLK library 4.54 in Window environment for one of the project. For smaller set the of data, it works. For data, which is moderate, it does not work and gives an error, which is given below: glp_alloc: no memory avaialable Error detected in file ..\src\env\alloc.c at line 91 I did some investigations on this: glp_intopttakes huge amount of CPU time and never come back also, after 15 minutes of program execution, it stops execution of the program and gives the above error: Following is the snippet of the code: masterLP = glp_create_prob(); //Create and assign pointer lp to new (empty) linear program masterTran = glp_mpl_alloc_wksp(); ret=glp_mpl_read_model(masterTran, masterModelFileName,1); //Read and store the problem from .mod file into the lp problem obj ret=glp_mpl_read_data(masterTran,masterDataFileName); ret = glp_mpl_generate(masterTran, NULL); glp_mpl_build_prob(masterTran, masterLP); glp_write_lp(masterLP,NULL, "master.lp"); glp_read_lp(masterLP,NULL,"master.lp"); ret = glp_simplex(masterLP, NULL); //Tell GLPK to optimize problem that "lp" points to glp_intopt(masterLP,NULL); masterOptObjVal = glp_mip_obj_val(masterLP); //Get the optimal objective value from the optimization Appreciate your help/suggestion in this issue. Thank you in advance.
