A clone of this RuleCondition object.

matches

public boolean matches(double[] othergenome)

Checks whether two conditions match or not.

Parameters:

othergenome - A double array specifying a condition to check against this condition.

Returns:

True if the two conditons match, otherwise false.

matches

public boolean matches(RuleCondition other)

Checks whether two conditions match or not.

Parameters:

other - A condition to check against this condition.

Returns:

True if the two conditons match, otherwise false.

randomValue

public double randomValue(int position)

Returns a valid randomly chosen value for the specified index in this rule, including the ``don't care'' symbol.

Parameters:

position - The index within this condition to query.

set

public void set(double[] newgenome)

Sets this condition to the supplied argument.

Parameters:

newgenome -

set

public void set(int position,
                double value)

Sets a particular position in this condition to the supplied value.

Parameters:

position - The index within this condition to set.

value - A double value specifying what value the position should be set to. This could be Condition.HASH to set it as a "don't care" symbol.
