Function Documentation

SCIP_DECL_SORTPTRCOMP ( SCIPpricerComp  )

compares two pricers w. r. to their priority

SCIP_DECL_SORTPTRCOMP ( SCIPpricerCompName  )

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

SCIP_PRICERDATA* SCIPpricerGetData ( SCIP_PRICER *  pricer)

gets user data of variable pricer

Parameters
pricervariable pricer
void SCIPpricerSetData ( SCIP_PRICER *  pricer,
SCIP_PRICERDATA *  pricerdata 
)

sets user data of variable pricer; user has to free old data in advance!

Parameters
pricervariable pricer
pricerdatanew variable pricer user data
const char* SCIPpricerGetName ( SCIP_PRICER *  pricer)

gets name of variable pricer

Parameters
pricervariable pricer
const char* SCIPpricerGetDesc ( SCIP_PRICER *  pricer)

gets description of variable pricer

Parameters
pricervariable pricer
int SCIPpricerGetPriority ( SCIP_PRICER *  pricer)

gets priority of variable pricer

Parameters
pricervariable pricer
int SCIPpricerGetNCalls ( SCIP_PRICER *  pricer)

gets the number of times, the pricer was called and tried to find a variable with negative reduced costs

Parameters
pricervariable pricer
int SCIPpricerGetNVarsFound ( SCIP_PRICER *  pricer)

gets the number of variables with negative reduced costs found by this pricer

Parameters
pricervariable pricer
SCIP_Real SCIPpricerGetSetupTime ( SCIP_PRICER *  pricer)

gets time in seconds used in this pricer for setting up for next stages

Parameters
pricervariable pricer
SCIP_Real SCIPpricerGetTime ( SCIP_PRICER *  pricer)

gets time in seconds used in this pricer

Parameters
pricervariable pricer
SCIP_Bool SCIPpricerIsActive ( SCIP_PRICER *  pricer)

returns whether the given pricer is in use in the current problem

Parameters
pricervariable pricer
SCIP_Bool SCIPpricerIsDelayed ( SCIP_PRICER *  pricer)

returns whether the pricer should be delayed until no other pricer finds a new variable

Parameters
pricervariable pricer
SCIP_Bool SCIPpricerIsInitialized ( SCIP_PRICER *  pricer)

is variable pricer initialized?

Parameters
pricervariable pricer
