SCIP_DECL_SORTPTRCOMP ( SCIPcomprComp )

compares two compressions w. r. to their priority

compares two compression methods w. r. to their delay positions and their priority

Definition at line 41 of file compr.c.

References NULL, and SCIP_Compr::priority.

SCIP_DECL_SORTPTRCOMP ( SCIPcomprCompName )

comparison method for sorting compressions w.r.t. to their name

comparison method for sorting heuristics w.r.t. to their name

Definition at line 53 of file compr.c.

References SCIPcomprGetName().

SCIP_COMPRDATA* SCIPcomprGetData ( SCIP_COMPR * compr )

gets user data of tree compression

Parameters
