Expressions

@parameter_function(model::InfiniteModel, func_expr, kwargs...)

Add an anonymous parameter function to the model model described by the keyword arguments kw_args and returns the object reference.

@parameter_function(model::InfiniteModel, var_expr == func_expr, kwargs...)

Add a parameter function to model described by the expression var_expr, the function expression func_expr, and the keyword arguments kwargs. The expression var_expr is used to define the parameter function references of the form varname[...] where the indexing matches the container syntax of other macros.

The expression func_expr determines the concrete Julia function that defines the behavior of parameter function and also specifies the infinite parameters it depends on. The accepted forms are:

• func(params...): where func is the function that takes supports of the infinite parameters params as input and outputs a scalar value.
• (params...) -> my_func_expr: where params are the infinite parameters and my_func_expr is the source code of the anonymous function.

The recognized keyword arguments in kwargs are the following:

• base_name: Sets the name prefix used to generate object names. It corresponds to the object name for scalar parameter function, otherwise, the object names are set to base_name[...] for each index ... of the axes axes.
• container: Specify the container type. Defaults to :Auto.

Examples

julia> @parameter_function(model, sin(t))
sin(t)

julia> func_vect = [sin, cos];

julia> @parameter_function(model, [i = 1:2] == func_vect[i](t))
2-element Array{GeneralVariableRef,1}:
 sin(t)
 cos(t)

julia> f(t_val, x_vals) = t_val + sum(x_vals)
f (generic function with 1 method)

julia> @parameter_function(model, pf == f(t, x))
pf(t, x)

julia> g(t_val, a; b = 0) = t_val + a + b
g (generic function with 1 method)

julia> @parameter_function(model, pf2[i = 1:2] == t -> g(t, i, b = 2 * i ))
2-element Array{GeneralVariableRef,1}:
 pf2[1](t)
 pf2[2](t)

parameter_function(func::Function, 
                   pref_inputs::Union{GeneralVariableRef, AbstractArray{GeneralVariableRef}, Tuple}; 
                   [name::String = [the name of `func`]]
                   )::GeneralVariableRef

Make a parameter function and return a GeneralVariableRef that can be embedded in InfiniteOpt expressions. This serves as a convenient wrapper for build_parameter_function and add_parameter_function. For an even more convenient definition method see @parameter_function.

Here func denotes the function that will take a support of infinite parameters as input (formatted like pref_inputs) and will return a scalar value. Specifically, func should be of the form:

func(paramvals...)::Float64

where the formatting of paramvals is analagous to point variables (and will be based on the tuple of infinite parameter references given in parameter_refs). Moreover, func must be a function that returns a scalar numeric value.

Errors if func will not take a support formatted like pref_inputs in combination with the fargs and fkwargs specified. Also errors if pref_inputs follow an invalid input format.

Example

julia> p_func = parameter_function(sin, t)
sin(t)

julia> p_func3 = parameter_function((t_supp) -> 2 * sin(2 * t_supp), t, name = "mysin")
mysin(t)

julia> p_func4 = parameter_function(t, name = "mysin") do t_supp
                    if t_supp <= 5
                        return sin(t_supp)
                    else 
                        return 2 * sin(2 * t_supp)
                    end
                 end

mysin(t)

build_parameter_function(
    _error::Function, 
    func::Function, 
    parameter_refs::Union{GeneralVariableRef, AbstractArray{<:GeneralVariableRef}, Tuple}
    )::ParameterFunction

Build an ParameterFunction object that employs a parameter function func that takes instances of the infinite parameter(s) as input. This can ultimately by incorporated into expressions to enable nonlinear infinite parameter behavior and/or incorporate data over infinite domains.

Here func should be of the form:

func(paramvals...)::Float64

where the formatting of paramvals is analagous to point variables (and will be based on the tuple of infinite parameter references given in parameter_refs).

Errors if the infinite parameter tuple is formatted incorrectly. The allowed format follows that of infinite variables. Also errors if the function doesn't accept a support realization of the parameter_refs as input.

Example

julia> f = build_parameter_function(error, sin, t);

ParameterFunction{F <: Function, VT <: VectorTuple}

                       [name::String])::GeneralVariableRef

A type for storing new nonlinear operators and their information that is ultimately for automatic differentiation. The constructor is of the form:

The optional function ∇f evaluates the first derivative, and the optional function ∇²f evaluates the second derivative.

∇²f may be provided only if ∇f is also provided.

Univariate syntax

If dim == 1, then the method signatures of each function must be:

• ∇²f(H::AbstractMatrix{T}, x::T...)::Nothing where {T<:Real}

Where the gradient vector g and Hessian matrix H are filled in-place. For the Hessian, you must fill in the non-zero lower-triangular entries only. Setting an off-diagonal upper-triangular element may error.

Example

julia> model = Model();

julia> @variable(model, x)
x

julia> f(x::Float64) = x^2

    [∇²f::Function];
    [name::Symbol = Symbol(f)]

It contains the needed information to create a variable type specifc reference (e.g., InfiniteVariableRef) via dispatch_variable_ref to obtain the correct subtype of DispatchVariableRef based off of index_type. This allows us to construct expressions using concrete containers unlike previous versions of InfiniteOpt which provides us a significant performance boost.
