Constructor Details

PopulationVector

public PopulationVector()

Creates an empty PopulationVector object.

PopulationVector

public PopulationVector(Integer[] P)

Creates an PopulationVector with content equal to the given matrix.

Parameters:

P - The matrix containing the vector elements

PopulationVector

public PopulationVector(int[] P)

Creates an PopulationVector with content equal to the given matrix.

Parameters:

P - The matrix containing the vector elements

PopulationVector

public PopulationVector(int k,
 int length)

Creates a new PopulationVector of specific lenth, where all elements are equal to a specific value.

Parameters:

k - The value of all elements

length - The length of the PopulationVector

Method Details

copy

public PopulationVector copy()

This method returns a copy of the current PopulationVector object. Position and delta stacks are disregarded.

Overrides:

copy in class EnhancedVector

Returns:

Copy of the initial PopulationVector object.

addVec

public PopulationVector addVec(EnhancedVector b)

Description copied from class: EnhancedVector

Adds two vectors. The vectors must be of the same size.

Overrides:

addVec in class EnhancedVector

Parameters:

b - Vector to add

Returns:

The result of the addition

subVec

public PopulationVector subVec(EnhancedVector b)

Overrides:

subVec in class EnhancedVector

Parameters:

b - Vector to add

Returns:

The result of the subtraction

changePopulation

public PopulationVector changePopulation(PopulationChangeVector n)

Changes the population by subtracting the supplied Population Change Vector

Parameters:

n - The PopulationChangeVector

Returns:

anyGreaterThan

public boolean anyGreaterThan(PopulationVector a)
