Field Detail

SolveTime

public static final IloCP.DoubleInfo SolveTime

Double info parameter. This information represents the time spent in the last solve including any extraction time (see IloCP.extract). That is, the time spent in the CP Optimizer search engine (in seconds) since the last call to IloCP.solve or IloCP.startNewSearch. Whether this measures "system time" or "wall-clock" time depends on the value of the TimeMode parameter.

ExtractionTime

public static final IloCP.DoubleInfo ExtractionTime

Double info parameter. This information represents the time spent extracting the model in the last solve. That is, the time spent in model extraction by the optimizer (in seconds) since the last call to IloCP.solve or IloCP.startNewSearch. Whether this measures "system time" or "wall-clock" time depends on the value of the TimeMode parameter.

TotalTime

public static final IloCP.DoubleInfo TotalTime

Double info parameter. This information represents the total time spent in the invoking instance of CP Optimizer search engine (in seconds) since it was created. Whether this measures "system time" or "wall-clock" time depends on the value of the TimeMode parameter.

EffectiveOptimalityTolerance

public static final IloCP.DoubleInfo EffectiveOptimalityTolerance

Double info parameter. This information represents the effective optimality tolerance observed after a problem optimization. It can be stronger than the one given by tolerance parameters. For example, for a minimization problem, if this information returns a value t and IloCP.getObjValue returns a value v, then the optimal objective value is guaranteed to be no less than v-t.
