Notes
|
By default, all solution routines of the Optimizer are deterministic - multiple invocations on the same data yield a reproducible algorithmic path. However, some of the log information produced may differ between two runs. In particular, wall clock time stamps in seconds may slightly vary between runs. Setting
DETERMINISTICLOG=1 suppresses all nondeterministic log information. All time stamps are reported as deterministic work units.
Setting
DETERMINISTICLOG=1 also suppresses memory usage information.
The degree of determinism of the Optimizer is governed by the user control
DETERMINISTIC.
The correct function of time limit controls such as
TIMELIMIT is not affected by this control.
This control does not guarantee a deterministic log for nonstandard values of the
MIPLOG control.
