Class COptQuestUserControlledVariable

java.lang.Object
  com.opttek.optquest.COptQuestVariable
      com.opttek.optquest.COptQuestUserControlledVariable

public class COptQuestUserControlledVariable
extends COptQuestVariable

The COptQuestUserControlledVariable class allows you to define a variable where you set the value of the variable. Unlike a COptQuestVariable whose possible value is determined by the OptQuest Engine, you provide the values for COptQuestUserControlledVariable objects.

COptQuestUserControlledVariable objects can be used in the mathematical expression of COptQuestStringConstraint objects or a COptQuestStringObjective object. For example, you may define a COptQuestUserControlledVariable that represents a risk calculation and use the risk value in a COptQuestStringConstraint that says risk must be less than or equal to n. In the COptQuestOptimization::Evaluate(COptQuestSolution) method, you would compute the risk value and use the COptQuestSolution.SetVariableValue() method to set the risk value in the solution. The OptQuestEngine would use this value when checking the constraint for feasiblity.

Constructor Detail

COptQuestUserControlledVariable

public COptQuestUserControlledVariable(java.lang.String name)

Constructor that assigns a name to the variable.

Parameters:

name - alphanumeric name. Note: the name can contain blanks or special characters. If the variable name is used in a COptQuestConstraintString equation and it contains non-alphnumeric characters, the name should be enclosed in square brackets []
