Moves Generators


Move Generators for Binary Vectors

Common Operator Parameters:

Parameter Description
BinaryVector The BinaryVector for which moves should be generated.
CurrentScope The current scope where the moves should be added as subscopes.
OneBitflipMove The moves that should be generated in subscopes.
Random The random number generator.

ExhaustiveBitflipMoveGenerator

Generates all possible one bitflip moves from a given binary vector.

StochasticOneBitflipMultiMoveGenerator

Randomly samples n from all possible one bitflip moves from a given binary vector.

StochasticOneBitflipSingleMoveGenerator

Randomly samples a single from all possible one bitflip moves from a given binary vector.


Move Generators for Permutation Encoding

Common Operator Parameters:

Parameter Description
CurrentScope The current scope where the moves should be added as subscopes.
!Permutation The permuation for which moves should be generated.

ExhaustiveInsertionMoveGenerator

Generates all possible insertion moves (3-opt) from a given permutation.

Additional Operator Parameters:

Move Generators for Real Vector Encoding

Common Operator Parameters:

Parameter Description
AdditiveMove The moves that should be generated in subscopes.
Bounds A 2 column matrix specifying the lower and upper bound for each dimension. If there are less rows than dimension the bounds vector is cycled.
CurrentScope The current scope where the moves should be added as subscopes.
Random The random number generator.
RealVector The real vector for which moves should be generated.
SampleSize The number of moves that should be generated.

StochasticNormalMultiMoveGenerator

Generates normal distributed moves from a given real vector.

Additional Operator Parameters:

Parameter Description
Sigma The standard deviation of the normal distribution. (Default: 1)

StochasticPolynomialMultiMoveGenerator

Generates polynomial moves from a given real vector.

Additional Operator Parameters:

Parameter Description
Contiguity Specifies whether the manipulation should produce far stretching (small value) or close (large value) manipulations with higher probability. Valid values must be greater or equal to 0. (Default: 2)
MaximumManipulation Specifies the maximum value that should be added or subtracted by the manipulation. If this value is set to 0 no mutation will be performed. (Default: 1)
