sets the timing mask of the presolver

Parameters

presol presolver timing timing mask of the presolver

Definition at line 663 of file presol.c.

References NULL, and SCIP_Presol::timing.

creates a presolver and includes it in SCIP

Note

method has all presolver callbacks as arguments and is thus changed every time a new callback is added in future releases; consider using SCIPincludePresolBasic() and setter functions if you seek for a method which is less likely to change in future releases

creates a presolver and includes it in SCIP.

Precondition

This method can be called if SCIP is in one of the following stages:

• SCIP_STAGE_INIT
• SCIP_STAGE_PROBLEM

Note

method has all presolver callbacks as arguments and is thus changed every time a new callback is added in future releases; consider using SCIPincludePresolBasic() and setter functions if you seek for a method which is less likely to change in future releases

Parameters

scip SCIP data structure name name of presolver desc description of presolver priority priority of the presolver (>= 0: before, < 0: after constraint handlers) maxrounds maximal number of presolving rounds the presolver participates in (-1: no limit) timing timing mask of the presolver presoldata presolver data

Creates a presolver and includes it in SCIP with its fundamental callback. All non-fundamental (or optional) callbacks as, e.g., init and exit callbacks, will be set to NULL. Optional callbacks can be set via specific setter functions. These are SCIPsetPresolCopy(), SCIPsetPresolFree(), SCIPsetPresolInit(), SCIPsetPresolExit(), SCIPsetPresolInitpre(), and SCIPsetPresolExitPre().

Note

if you want to set all callbacks with a single method call, consider using SCIPincludePresol() instead
