Hi, all I am using GLPK now. the version is 4.45. I use it in Cygwin I have a problem. I set up a row with upper bound 0 and lower bound 0, the when I run it. Problem appears. Code is glp_set_row_bnds(lp, 1, GLP_DB, 0.0, 0.0); output is glp_simplex: row 1: lb = 0, ub = 0; incorrect bounds Then I change the code glp_set_row_bnds(lp, 1, GLP_DB, 0.0, 0.001); and it works. Does this mean that we cannot set both bound equal? But in the GLPK reference Manual, on page 13, it says "Bounds of variables can be nite as well as in nite. Besides, lower and upper bounds can be equal to each other." Thanks.
