The Expression type exposes the following members.

Constructors

	Name	Description
	Expression	Initializes a new instance of the Expression class

Methods

	Name	Description
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Evaluate	Evaluates the expression using the specified variable values.
	Finalize	Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	Sum(IEnumerable<(Of <<'(Double>)>>))	Sums up the specified values.
	Sum(IEnumerable<(Of <<'(Expression>)>>))	Sums the specified expressions.
	Sum(IEnumerable<(Of <<'(Term>)>>))	Sums the specified terms.
	Sum(IEnumerable<(Of <<'(Variable>)>>))	Sums the specified variables.
	Sum(Int32, Int32, Func<(Of <<'(Int32, Expression>)>>))	Sums the specified range of expressions.
	Sum(Int32, Int32, Func<(Of <<'(Int32, Term>)>>))	Sums the specified range of terms.
	ToString	Returns a String that represents the current Object. (Inherited from Object.)

Operators

	Name	Description
	Addition(Double, Expression)	Adds a constant to an expression
	Addition(Expression, Expression)	Implements the operator +.

	Inequality(Expression, Variable)	Please construct inequalities using <= and >=
	Inequality(Expression, Double)	Please construct inequalities using <= and >=
	Inequality(Variable, Expression)	Please construct inequalities using <= and >=
	LessThanOrEqual(Double, Expression)	Implements the operator <=.
	LessThanOrEqual(Expression, Expression)	Implements the operator <=.
	LessThanOrEqual(Expression, Variable)	Implements the operator <=.
	LessThanOrEqual(Expression, Double)	Implements the operator <=.
	LessThanOrEqual(Variable, Expression)	Implements the operator <=.
	Multiply(Double, Expression)	Implements the operator *.
	Multiply(Expression, Expression)	Implements the operator *.
	Multiply(Expression, Double)	Implements the operator *.
	Subtraction(Double, Expression)	Implements the operator -.

Properties

	Name	Description
	Constant	Gets the constant of this expression.
	ExpressionLowerEstimate	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!
	ExpressionUpperEstimate	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!
	isLinear	Gets or sets a value indicating whether this instance is linear.
	Terms	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.
	Variables	Gets the variables in this expression.
