◆ getDecisionBuilder()

DecisionBuilder com.google.ortools.constraintsolver.DefaultPhaseParameters.getDecisionBuilder ( )

When defined, this overrides the default impact based decision builder.

Definition at line 239 of file DefaultPhaseParameters.java.

◆ getDisplayLevel()

int com.google.ortools.constraintsolver.DefaultPhaseParameters.getDisplayLevel ( )

This represents the amount of information displayed by the default search.
NONE means no display, VERBOSE means extra information.

Definition at line 207 of file DefaultPhaseParameters.java.

◆ getHeuristicNumFailuresLimit()

int com.google.ortools.constraintsolver.DefaultPhaseParameters.getHeuristicNumFailuresLimit ( )

The failure limit for each heuristic that we run.

Definition at line 161 of file DefaultPhaseParameters.java.

◆ getHeuristicPeriod()

int com.google.ortools.constraintsolver.DefaultPhaseParameters.getHeuristicPeriod ( )

The distance in nodes between each run of the heuristics. A
negative or null value will mean that we will not run heuristics
at all.

Definition at line 147 of file DefaultPhaseParameters.java.

◆ getInitializationSplits()

int com.google.ortools.constraintsolver.DefaultPhaseParameters.getInitializationSplits ( )

Maximum number of intervals that the initialization of impacts will scan
per variable.

Definition at line 111 of file DefaultPhaseParameters.java.

◆ getPersistentImpact()

boolean com.google.ortools.constraintsolver.DefaultPhaseParameters.getPersistentImpact ( )

Whether to keep the impact from the first search for other searches,
or to recompute the impact for each new search.

Definition at line 177 of file DefaultPhaseParameters.java.

◆ getRandomSeed()

int com.google.ortools.constraintsolver.DefaultPhaseParameters.getRandomSeed ( )

Seed used to initialize the random part in some heuristics.

Definition at line 191 of file DefaultPhaseParameters.java.

◆ getRunAllHeuristics()

boolean com.google.ortools.constraintsolver.DefaultPhaseParameters.getRunAllHeuristics ( )

The default phase will run heuristics periodically. This parameter
indicates if we should run all heuristics, or a randomly selected
one.

Definition at line 129 of file DefaultPhaseParameters.java.

◆ getUseLastConflict()

boolean com.google.ortools.constraintsolver.DefaultPhaseParameters.getUseLastConflict ( )

Should we use last conflict method. The default is false.

Definition at line 221 of file DefaultPhaseParameters.java.

◆ getValueSelectionSchema()

int com.google.ortools.constraintsolver.DefaultPhaseParameters.getValueSelectionSchema ( )

This parameter describes which value to select for a given var.

Definition at line 95 of file DefaultPhaseParameters.java.

◆ getVarSelectionSchema()

int com.google.ortools.constraintsolver.DefaultPhaseParameters.getVarSelectionSchema ( )

This parameter describes how the next variable to instantiate
will be chosen.
