Detailed Description

Wrapper around Optimizer and CostFunction classes to work on simple lambda functions.

Example usage:

auto costFunction = [&](int n, const double* x) { return ...; };
OptimizerWrapper ow(costFunction, 3);
ow.compute();

Public Member Functions
	OptimizerWrapper (std::function< double(int, const double *)> cf, int dim, int type=34)
	Constructor with lambda cost function, dimension and optional NLopt type (BOBYQA by default)
OptimizerNL &	opt ()
	Provides access to the underlying OptimizerNL instance for all detailed settings.
int	compute (std::vector< double > &pars)
	Executes the optimization with the given initial parameters.
int	compute ()
	Executes the optimization with zero-initialized parameters.
double	evaluate (int n, const double *x, double *dx=0) override
	Forwards the cost function evaluation to the lambda function (derivatives not supported)

Protected Attributes
std::function< double(int, const double *)>	m_cf
	Cost function.
OptimizerNL	m_opt
	Optimizer instance.
