Executing the warehouse project with scalable data

Explains how to pause and observe the results of the suspended execution.

Basic Configuration is predefined as the default run configuration to be executed. Since it is not the configuration you want to work on, you will first make another run configuration the default one.

The scalable model has been designed to be solved by the CPLEX engine in several seconds so that you have time to observe and interact with the execution process. To experience such interaction and observe the results, you are now going to start, then suspend, the execution and observe the output in the Statistics tab.

Note that the small example models solve very quickly. In the procedure described here, the Pause button appears briefly, and the Continue button may take some time to appear.

  1. Right-click on Scalable data and choose Set as Default.

    This configuration name is now labeled as the new default.

  2. To execute this run configuration, right-click on Scalable data, and select Run this.
  3. In the Execution toolbar, the Pause the current solve button Pause button appears. Click this button just after launching the solve to interrupt the process and examine the current solution.

    (See What happens when you execute a run configuration in the IDE Reference for details.)

  4. Click the Statistics tab.

    See Examining the statistics and progress chart (MP) to understand what you see at this stage of the execution process.

  5. The Pause button is replaced with the Continue the current solve button Continue button. Click to continue and wait until execution is complete.

    The IDE returns to the running state and completes the solve.

    You will see the shape of the green line that represents the best integer solution change as more iterations are made.
