CGAL::Quadratic_program_options

#include <CGAL/QP_options.h>

This is a class used for passing options to the linear and quadratic programming solvers. Currently, we support only options referring to

The idea is that this list grows in the future.

Quadratic_program_options options;
	constructs an instance of Quadratic_program_options where all available options are at their defaults.

Here we just have set/get pairs for any option type.

void	options.set_verbosity ( int verbosity)
		sets the verbosity of the solver to the value verbosity when options is passed to any of the four solution functions. The provided value must be a number between 0 and 5. Verbosity 0 is the default and results in the solver running silently. Verbosity 1 prints a short summary of every iteration. Higher verbosity values print more information about the solution process, but these are mainly for debugging purposes and have no effect if you compile with `CGAL_QP_NO_ASSERTIONS` or `NDEBUG`.

int	options.get_verbosity ()	returns the verbosity level of options.

void	options.set_pricing_strategy ( Quadratic_program_pricing_strategy pricing_strategy)
		sets the pricing strategy of the solver to the value pricing_strategy when options is passed to any of the four solution functions. The pricing strategy controls how the solver proceeds from any intermediate solution. The provided value must be QP_FULL_EXACT (the default), or QP_EXACT_BLAND. The latter value guarantees that the solver does not internally cycle.

Quadratic_program_pricing_strategy
	options.get_pricing_strategy ()	returns the pricing strategy of options.

void	options.set_auto_validation ( bool validate)
		sets the automatic validation mode of the solver to the value validate. The default is false. By providing value true you can tell the solver to automatically check whether the program has correctly been solved, see the Validity section of the class Quadratic_program_solution.

bool	options.get_auto_validation ()	returns the validation mode of options.
