Constructor Detail

COptQuestDiscreteVariable

public COptQuestDiscreteVariable(java.lang.String name,
                                 double lowerBound,
                                 double upperBound,
                                 double step)

Constructor that assigns a name to the variable and sets the lower bound, upper bound and step size.

Parameters:

name - alphanumeric name. Note: the name can contain blanks or special characters. If the variable name is used in a COptQuestStringConstraint equation, the name should be enclosed in square brackets [] in the COptQuestStringConstraint string equation.

lowerBound - a value between -pow(2,31) and +pow(2,31)-1

upperBound - a value between -pow(2,31) and +pow(2,31)-1

step - the step size which can be any value that is less than or equal to the difference between the upper bound and the lower bound.

                                 double upperBound,
                                 double step)

Constructor that sets the lower bound,upper bound and step size.

Parameters:

lowerBound - a value between -pow(2,31) and +pow(2,31)-1

upperBound - a value between -pow(2,31) and +pow(2,31)-1

step - the step size which can be any value that is less than or equal to the difference between the upper bound and the lower bound.
