Re: [Help-glpk] different result

[Xypron]

Hello Ajeng,

you do not provide the excel solution. Hence it is impossible to tell if it is valid.

glpsol has option -r to read a solution from a file.

Use command printf to calculate the right hand side of each constraint and to check if it is met by the Excel solution.

Best regards
