Initial value:

= R"==(
problem types:
    dl: Dynamically loaded problem using the DLProblem class.
        Specify the name of the registration function using the
        problem.register option, e.g. problem.register=register_alpaqa_problem.
        Further options can be passed to the problem using
        problem.<key>[=<value>].
    cs: Load a CasADi problem using the CasADiProblem class.
        If a .tsv file with the same name as the shared library file exists,
        the bounds and parameters will be loaded from that file. See
        CasADiProblem::load_numerical_data for more details.
        The problem parameter can be set using the problem.param option.
    cu: Load a CUTEst problem using the CUTEstProblem class.
 
options:
    --full-print
        Print the full gradients.
    --no-hessians
        Do not check any Hessian matrices.
    --seed=<seed>
        Seed for the random number generator.
