public sealed class Min : OperatorExpression, IOperator, IMin, IOperatorExpression

Constructors

Min(IEnumerable<Expression>, Nullable<Double>)

Initializes a new instance of the Min class.

Declaration
public Min(IEnumerable<Expression> expressions, double? bigM = default(double? ))
Parameters
Type Name Description
System.Collections.Generic.IEnumerable<Expression> expressions

The expressions.
System.Nullable<System.Double> bigM

Large number, only used if the bounds of the variables of the expressions are non-finite. It should be chosen large enough, so that the solution space is not cut. But choosing this value too large, it can cause numerical errors.

Properties

IsLinear

Gets a value indicating whether this operator always preserves linearity when used with linear expressions. Linearity can be re-established when modelling through linear constraints with new variables, i.e., z=min(expression1,expression2) and w \in { 0,1} for two expressions.

Declaration
public override bool IsLinear { get; }
Property Value
Type Description
System.Boolean

true if linearity is preserved otherwise, false.
Overrides

PreservesLinearity

Gets a value indicating whether this operator always preserves linearity when used with terms. Linearity can be re-established when modelling through linear constraints with new variables, i.e., z=min(expression1,expression2) and w \in { 0,1} for two expresssions

Declaration
public override bool PreservesLinearity { get; }
Property Value
Type Description
System.Boolean

true if linearity is preserved otherwise, false.
Overrides

RepresentingVariable

A variable that can later be set to the representing variable when a model transformation for removing Min- expressions is applied.

Declaration
public Variable RepresentingVariable { get; set; }
Property Value
Type Description
