[Symphony] biobjective problems

[Papis Wongchaisuwat]

I found  bicriteria.c file in Examples. I tried running with the data set and I got several solutions as I am supposed to get. However, I am not sure whether I got a correct result.These are some parts of bicriteria.c file#include "symphony.h"
int main(int argc, char **argv){
   sym_environment *env = sym_open_environment();   sym_parse_command_line(env, argc, argv);   sym_load_problem(env);
   sym_set_obj2_coeff(env, 1, -1);
   sym_mc_solve(env);
   sym_close_environment(env);
   return(0);
}
#endif
Does anyone know what sym_set_obj2_coeff(env, 1, -1) means?  When should I use 1 or -1?My sample data is a minimization problem.
Thank you,Papis
