I implemented my mathematical model using Ilog Cplex ver 2.7. the decimal part of the objective function is very small and cplex returns 0 so the cplex abandons part of the objective function (so the objective function is not really optimized). Is there a way to increase the accuracy so that the cplex takes the max of decimal into account? I have created a file ops to change the decimal prision from 4 to 10 but cplex always does not take into account the figures after the decimal point for you well understands to see the image below.?

In that part you cannot change the display precision. But as said in this post you may see more in the statistics tab.

Or you may use scripting to get any precision you need.

  • How I can use scripting to get precision? the cplex does not really minimize the objective function when we have decimal tea very small. – Hamza Feb 26 '19 at 12:52
