LnsPhaseOptions

public LnsPhaseOptions(int failureLimitPerRestart,
 int freezeRatePercent,
 double randomSwapProbability,
 long randomSeed,
 BlackBoxSearch.FragmentSelectionStrategy fragmentSelectionStrategy)

Creates an instance of a LnsPhaseOptions record class.

Parameters:

failureLimitPerRestart - the value for the failureLimitPerRestart record component

freezeRatePercent - the value for the freezeRatePercent record component

randomSwapProbability - the value for the randomSwapProbability record component

randomSeed - the value for the randomSeed record component

fragmentSelectionStrategy - the value for the fragmentSelectionStrategy record component

 int freezeRatePercent,
 double randomSwapProbability,
 long randomSeed)

Method Details

defaults

public static BlackBoxSearch.LnsPhaseOptions defaults()

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with '=='.

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

failureLimitPerRestart

public int failureLimitPerRestart()

Returns the value of the failureLimitPerRestart record component.

Returns:

the value of the failureLimitPerRestart record component

freezeRatePercent

public int freezeRatePercent()

Returns the value of the freezeRatePercent record component.

Returns:

the value of the freezeRatePercent record component

randomSwapProbability

public double randomSwapProbability()

Returns the value of the randomSwapProbability record component.

Returns:

the value of the randomSwapProbability record component

randomSeed

public long randomSeed()

Returns the value of the randomSeed record component.

Returns:

the value of the randomSeed record component

fragmentSelectionStrategy

public BlackBoxSearch.FragmentSelectionStrategy fragmentSelectionStrategy()

Returns the value of the fragmentSelectionStrategy record component.

Returns:

the value of the fragmentSelectionStrategy record component
