Hi, Any guru has the solution to output ranging files for the MAC? I can not get my ranging report output to the cplex.opt. Here is the code I used:
model Invest /all/;
$onecho > cplex.opt
objrng all
rhsrng all
$offecho
Invest.OptFile=1;
solve Invest using lp maximizing z;
The cplex.opt only has two lines:
objrng all
rhsrng all
Here follows the log, it seems all right.
Reading parameter(s) from “/Users/cplex.opt”
objrng all
rhsrng all
Finished reading from “/Users/ypeng/Downloads/SMU/EMIS8378/Homework3/cplex.opt”
