DisjunctiveProgramming.@disjunctionMacro
@disjunction(model, expr, kw_args...)

Add a disjunction described by the expression expr, which must be a Vector of LogicalVariableRefs.

@disjunction(model, ref[i=..., j=..., ...], expr, kw_args...)

Add a group of disjunction described by the expression expr parameterized by i, j, ..., which must be a Vector of LogicalVariableRefs.

In both of the above calls, a Disjunct tag can be added to create nested disjunctions.

The recognized keyword arguments in kw_args are the following:

  • base_name: Sets the name prefix used to generate constraint names. It corresponds to the constraint name for scalar constraints, otherwise, the constraint names are set to base_name[...] for each index ... of the axes axes.
  • container: Specify the container type.
  • exactly1: Specify a Bool whether a constraint should be added to only allow selecting one disjunct in the disjunction.

To create disjunctions without macros, see disjunction.

source
DisjunctiveProgramming.@disjunctionsMacro
@disjunctions(model, args...)

Adds groups of disjunctions at once, in the same fashion as the @disjunction macro.

The model must be the first argument, and multiple disjunctions can be added on multiple lines wrapped in a begin ... end block.

The macro returns a tuple containing the disjunctions that were defined.

Example

julia model = GDPModel(); @variable(model, w); @variable(model, x); @variable(model, Y[1:4], LogicalVariable); @constraint(model, [i=1:2], w == i, Disjunct(Y[i])); @constraint(model, [i=3:4], x == i, Disjunct(Y[i])); @disjunctions(model, begin [Y[1], Y[2]] [Y[3], Y[4]] end);`

source
DisjunctiveProgramming.binary_variableMethod
binary_variable(vref::LogicalVariableRef)::JuMP.AbstractVariableRef

DisjunctiveProgramming.binary_variableMethod

-)

Create a disjunction comprised of disjuncts with indicator variables disjunct_indicators and add it to model. For nested disjunctions, the nested_tag is required to indicate which disjunct it will be part of in the parent disjunction. By default, exactly1 adds a constraint of the form @constraint(model, disjunct_indicators in Exactly(1)) only allowing one of the disjuncts to be selected; this is required for certain reformulations like Hull. For nested disjunctions, exactly1 creates a constraint of the form @constraint(model, disjunct_indicators in Exactly(nested_tag.indicator)). To conveniently generate many disjunctions at once, see @disjunction and @disjunctions.

DisjunctiveProgramming.BigMType
BigM{T} <: AbstractReformulationMethod

A type for using the big-M reformulation approach for disjunctive constraints.

  • value::T: Big-M value (default = 1e9).
  • tight::Bool: Attempt to tighten the Big-M value (default = true)?
source
DisjunctiveProgramming.ConstraintDataType
ConstraintData{C <: JuMP.AbstractConstraint}

A type for storing constraint objects in GDPData and any meta-data they possess.

Fields

  • constraint::C: The constraint.
  • name::String: The name of the proposition.
source
DisjunctiveProgramming.DisjunctType
Disjunct

Used as a tag for constraints that will be used in disjunctions. This is done via the following syntax:

julia> @constraint(model, [constr_expr], Disjunct)
 
-julia> @constraint(model, [constr_expr], Disjunct(lvref))

where lvref is a LogicalVariableRef that will ultimately be associated with the disjunct the constraint is added to. If no lvref is given, then one is generated when the disjunction is created.

source
DisjunctiveProgramming.DisjunctionType
Disjunction{M <: JuMP.AbstractModel} <: JuMP.AbstractConstraint

A type for a disjunctive constraint that is comprised of a collection of disjuncts of indicated by a unique LogicalVariableIndex.

Fields

  • indicators::Vector{LogicalVariableref}: The references to the logical variables

(indicators) that uniquely identify each disjunct in the disjunction.

  • nested::Bool: Is this disjunction nested within another disjunction?
source
DisjunctiveProgramming.GDPModelMethod
GDPModel([optimizer]; [kwargs...])::JuMP.Model
+julia> @constraint(model, [constr_expr], Disjunct(lvref))

where lvref is a LogicalVariableRef that will ultimately be associated with the disjunct the constraint is added to. If no lvref is given, then one is generated when the disjunction is created.

source
DisjunctiveProgramming.DisjunctionType
Disjunction{M <: JuMP.AbstractModel} <: JuMP.AbstractConstraint

DisjunctiveProgramming.HullType

A type for using the convex hull reformulation approach for disjunctive constraints.

Fields

  • value::T: epsilon value for nonlinear hull reformulations (default = 1e-6).
source
DisjunctiveProgramming.LogicalType
Logical{T}

Tag for creating logical variables using @variable. Most often this will be used to enable the syntax:

@variable(model, var_expr, Logical, [kwargs...])

which creates a LogicalVariable that will ultimately be reformulated into a binary variable of the form:

@variable(model, var_expr, Bin, [kwargs...])

To include a tag that is used to create the reformulated variables, the syntax becomes:

@variable(model, var_expr, Logical(MyTag()), [kwargs...])

which creates a LogicalVariable that is associated with MyTag() such that the reformulation binary variables are of the form:

@variable(model, var_expr, Bin, MyTag(), [kwargs...])
source
DisjunctiveProgramming.LogicalVariableType
LogicalVariable <: JuMP.AbstractVariable

A variable type the logical variables associated with disjuncts in a Disjunction.

Fields

  • fix_value::Union{Nothing, Bool}: A fixed boolean value if there is one.
  • start_value::Union{Nothing, Bool}: An initial guess if there is one.
