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.
