Properties

  NameDescription
Public propertyConstant
Gets the constant of this expression.
Public propertyExpressionLowerEstimate
Gives a lower estimate on the value of an Expression. ToDO: Very experimental. Should be able to estimate linear combinations of variables with finite bounds. In the default case -infinity is returned!
Public propertyExpressionUpperEstimate
Gives an upper estimate in the value of an Expression. ToDO: Very experimental. Should be able to estimate linear combinations of variables with finite bounds. In the default case -infinity is returned!
Public propertyisLinear
Gets or sets a value indicating whether this instance is linear.
Public propertyTerms
Gets a list of the terms in this expression. It does not contain any operators and does not tell you anything aobut how they are combined with operators.
Public propertyVariables
Gets the variables in this expression.
