Method Detail

sameSign

public static boolean sameSign(double x,
                               double y)

check if x and y are with the same sign

Parameters:

x -

y -

Returns:

hasAdjustRoom

public static boolean hasAdjustRoom(double target,
                                    LimitType targetLimit,
                                    double resource,
                                    LimitType resourceLimit,
                                    boolean positiveSen)

The resource variable is used to adjust the target variable. In the case of target variable violation, check if the resource has adjustment room to change the target variable.

Parameters:

target - target variable to be controlled

targetLimit - target variable limit

resource - resource variable to be adjusted to control the target variable

resourceLimit - resource variable limit

positiveSen - adjustment sensitivity sign. If positive, increase the resource variable will result in increasing target variable.

Returns:

discreteValue

public static double discreteValue(double value,
                                   int numSteps,
                                   double stepSize)
