Barrier Display

Type

Selection

Range

The settings listed below

Default

None

The setting of this option determines the level of barrier progress information to be displayed while solving a mixed integer problem. At the default level, no progress information is displayed. At the level “Normal”, “normal” setup and iteration information is displayed (see the section “Barrier Input & Output” in Chapter 2 of the CPLEX documentation for a complete interpretation of normal display information). At a setting of “Diagnostics”, additional diagnostic information is displayed which may be useful when seeking technical support. Possible values are:

  • None

  • Normal

  • Diagnostics

Note

  • Logging information is only reported if the option Status Display is switched on.

  • Barrier logging is only reported if the option MIP Display is set to ‘Nth node + LP display for root node’ or ‘Nth node + LP display for all nodes’.

  • The logging information is written to the status file ‘ODH-CPLEX 5.3.log’ if the general solvers option Solver Listing Messages is set to ‘All’. The status file is placed in the log directory of the current project.

  • The logging information is written to the AIMMS message window if the general solvers option Solver Window Messages is set to ‘All’.
