	Profiler (std::shared_ptr< fit_app::IFitBackend > minimizer, ProfilerMode mode=ProfilerMode::MINUIT)

ProfileResult	profile (std::shared_ptr< ILikelihood > base, const ProfileRequest &pr) const
	Profiles a likelihood according to a request.

Detailed Description

Minimizes a likelihood over free parameters subject to fixed constraints.

The profiler supports two modes:

• ProfilerMode::MINUIT, which delegates to the configured fit backend,
• ProfilerMode::LAPLACE_NUISANCE, which attempts a fast Laplace approximation for nuisance-only profiling and falls back to Minuit when the request is incompatible or the approximation fails.

Constructor & Destructor Documentation

Profiler()

Profiler::Profiler	(	std::shared_ptr< fit_app::IFitBackend >	minimizer,
		ProfilerMode	mode = ProfilerMode::MINUIT
	)

Constructs a profiler.

Parameters

minimizer	Fit backend used for numerical minimization and fallbacks.
mode	Profiling algorithm selected for future calls.

Definition at line 85 of file Profiler.cpp.

Member Function Documentation

profile()

ProfileResult Profiler::profile	(	std::shared_ptr< ILikelihood >	base,
		const ProfileRequest &	pr
	)		const

Profiles a likelihood according to a request.

If no free parameters are provided, the method evaluates the likelihood directly at the fixed point. Otherwise, it dispatches to the configured profiling mode.

Parameters

base	Likelihood to profile.
pr	Fixed/free parameter specification and warm-start vector.

Returns

Profile result containing the profiled NLL, argmin and convergence status.

Exceptions

std::runtime_error

for inconsistent request dimensions or invalid fixed parameter indices.
