Control parameters
This module extends the getparam function and the setparam procedure in order to access all the control and problem parameters of Optimizer (for example the problem attribute LPSTATUS is mapped to the mmxprs control parameter XPRS_lpstatus). In addition to these, the following control parameters are also defined (see the note on inheritance of parameters settings in Section The problem type mpproblem.xprs when working with multiple problems):
|
Reorder matrix columns before loading the problem.
|
|
|
Handling of duplicate solutions during an enumeration.
|
|
|
Maximum number of solutions to be saved during an enumeration.
|
|
|
Number of solutions found during the last enumeration.
|
|
|
Optimizer version number.
|
|
|
Enable/disable loading of MPS names into the Optimizer.
|
|
|
Size of the pool of matrix updates.
|
|
|
Optimizer problem pointers.
|
|
|
Read/set the problem name used by the Optimizer.
|
|
|
Enable/disable active detection of model interruption.
|
|
|
Enable/disable message printing by the Optimizer.
|
setparam("XPRS_verbose", true) ! Turn on message printing
pstat:= getparam("XPRS_lpstatus") ! Get the problem LP optimization status
writeln("Best bound=", getparam("XPRS_bestbound")) ! Display the best bound value
