Hello Esma,

an error occured in function
void chuzc(struct csa *csa, double rtol)
when choosing a non-basic column.

If you are calling the simplex solver directly you could try settting
glp_smcp-r_test = GLP_RT_ST
to avoid the error.

@Andrew

The coding is unclear to me:

If no non-basic variable has been chosen on the first pass then the
function sets csa->q = 0 and is happy.

If no non-basic variable has been chosen on the second pass then the
error is raised.

Best regards

Xypron
