Constructor Detail

CubeRootFunction

public CubeRootFunction()

Construct a CubeRootFunction with no children.

CubeRootFunction

public CubeRootFunction(Node<java.lang.Double> child)

Construct a CubeRootFunction with one child. When evaluated, the child will be first evaluated, with the result cube-rooted.

Parameters:

child - The child which cube root will be performed on.

Method Detail

evaluate

public java.lang.Double evaluate()

Evaluating a CubeRootFunction involves evaluating the child first then performing cube root on the result.

Specified by:

evaluate in class Node<java.lang.Double>

Returns:

The result of evaluating the candidate program.

getFunctionName

public java.lang.String getFunctionName()

Get the unique name that identifies this function.

Specified by:

getFunctionName in class FunctionNode<java.lang.Double>

Returns:

the unique name for the CubeRootFunction which is CBRT.
