load_numerical_data()

template<Config Conf>

void load_numerical_data	(	const std::filesystem::path &	filepath,
		char	sep = ','
	)

Load the numerical problem data (bounds and parameters) from a CSV file.

The file should contain 8 rows, with the following contents:

1. U lower bound [nu]
2. U upper bound [nu]
3. D lower bound [nc]
4. D upper bound [nc]
5. D_N lower bound [nc_N]
6. D_N upper bound [nc_N]
7. x_init [nx]
8. param [p]

Line endings are encoded using a single line feed (\n), and the column separator can be specified using the sep argument.

penalty_alm_split

template<Config Conf>

index_t penalty_alm_split = 0

Components of the constraint function with indices below this number are handled using a quadratic penalty method rather than using an augmented Lagrangian method.

Specifically, the Lagrange multipliers for these components (which determine the shifts in ALM) are kept at zero.

index_t penalty_alm_split_N = 0
