# Create a model

    Dict{Int,Float64}(1 => 0.0, 3 => 0.4, 5 => -4.4),
    Dict{Tuple{Int,Int},Float64}((1, 3) => -0.8, (1, 5) => 6.0);

    offset = 1.93,
    domain = :bool,
    metadata = Dict("id" => 2, "description" => "Model 2 ~ Simple model with solutions")
)

# Write using D-Wave style (default)
QUBOTools.write_model("output.qubo", model, QUBOTools.Format{:qubo}(style=:dwave))

# Or write using MQLib style
QUBOTools.write_model("output.qubo", model, QUBOTools.Format{:qubo}(style=:mqlib))
