Hello
GLPK does not use exact math for solving MIP problems. Hence rounding
errors may occur.
What is the value range for Xmax67_134, and Xmax67_136? Can you replace
999,999 by a smaller value?
Best regards

In my lp file, there are 2 constraint voilated by solving in GLPK:
Xmax67_134 - 999999 B67_134BB<= 0
Xmax67_136 - 999999 B67_136BB<= 0
B67_134BB and B67_136BB are both binary variables. The solution given by
GLPK is following:
Row name Activity Lower bound Upper bound
Xmax67_134 6.8975 0
B67_134BB * 0 0 1
Xmax67_136 0.7975 0
B67_136BB * 0 0 1
How could GLKP give a solution that is not feasible?
Thanks.
