Methods

	Name	Description
	DataBind	Binds the data to the solver context.
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetIndexes<T>	Returns the indexes from a parameter object.
	GetIndexFieldGetters<T>	Creates get accessors for each index.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	SetIndexSet	Returns the specified index set.
	ToString()	Converts a parameter to its equivalent string representation. (Overrides Object.ToString().)
	ToString(String, IFormatProvider)	Converts a term to its equivalent string representation. (Inherited from Term.)
	VerifyModelNotFrozen	Verifies that the associated model is not frozen.

Remarks

Random parameters are used to model randomness in input data. Random parameters can be discrete or continuous, and can be used where non-random parameters or constants would normally be used in constraints. The RandomParameter class is the base class for a number of commonly used random distributions, including uniform, normal, and log normal. ScenariosParameter is a special type of random parameter, for which each scenario contains a value and a probability.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
