Displaying all variables

  • Displaying all variables:
    All the variables and their reduced costs can be displayed simultaneously by using the command
    display {j in 1.._nvars} (_varname[j],_var[j],_var[j].rc);
    
    (See page 249 of the AMPL text.)
  • Displaying all shadow prices:
    All the constraints and their shadow prices can be displayed simultaneously by using the command
    display {j in 1.._ncons} (_conname[j],_con[j]);
