Documentation

See the documentation for ParametricOptInterface.jl, as well as tutorials that use ParametricOptInterface in the JuMP documentation.

Use with JuMP

Use ParametricOptInterface with JuMP by following this brief example:

julia> using JuMP, HiGHS

julia> import ParametricOptInterface as POI

julia> model = Model(() -> POI.Optimizer(HiGHS.Optimizer));

julia> set_silent(model)

julia> @variable(model, x)
x

julia> @variable(model, p in Parameter(1))
p

julia> @constraint(model, x + p >= 3)
x + p ≥ 3

julia> @objective(model, Min, 2x)
2 x

julia> optimize!(model)

julia> value(x)
2.0

julia> set_parameter_value(p, 2.0)

julia> optimize!(model)

julia> value(x)
1.0
