It might be even better if the API has routines to
calculate the max increase and max decrease of the
bounds, for example:
/**sensitivity bounds for coeficient in the objective*/
glp_coef_sensit_bounds(GLP* lp, int var_idx,
double* max_dec, double* max_inc);,
/**sensitiviy bounds for the upper/lower bounds of a constraint*/
glp_con_bounds_sensit(GLP* lp, int con_idx,
double* max_dec_lb, double* max_inc_lb,
double* max_dec_ub, double* max_inc_ub);
/**sensitiviy bounds for the upper/lower bounds of a variable*/
glp_var_bounds_sensit(GLP* lp, int var_idx,
double* max_dec_lb, double* max_inc_lb,
double* max_dec_ub, double* max_inc_ub);
