48 * This class defines the interface for constraint handlers implemented in C++. Note that there are pure virtual
49 * functions (these have to be implemented). These functions are: scip_trans(), scip_enfolp(), scip_enforelax(),

114 int sepafreq, /**< frequency for separating cuts; zero means to separate only in the root node */
115 int propfreq, /**< frequency for propagating domains; zero means only preprocessing propagation */
116 int eagerfreq, /**< frequency for using all instead of only the useful constraints in separation,
118 int maxprerounds, /**< maximal number of presolving rounds the constraint handler participates in (-1: no limit) */
