This file contains a C++ implementation of the basinhopping algorithm. This code relies on the Google Ceres local minimization functions, and is inspired by the SciPy implementation found in scipy.optimize

Function Documentation

void pallas::dump	(	const Basinhopping::HistoryOutput &	h,
		HistoryWriter &	writer
	)

Dumps the system state contained in the history output into the stream contained by the writer.

Parameters

h	Basinhopping::HistoryOutput. State of the system for a specific iteration.
writer	HistoryWriter. Object responsible for writing the history output to a stream.

void pallas::Solve	(	const Basinhopping::Options &	options,
		const GradientProblem &	problem,
		double *	parameters,
		Basinhopping::Summary *	summary
	)

Helper function that avoids going through the interface of the pallas::Basinhopping class.

The specified options are used to setup a basinhopping instance which is then used to minimize the GradientProblem. The optimal solution is stored in parameters and a summary of the global optimization can be found in summary.

Parameters

options	pallas::Basinhopping::Options. Options used to configure the optimization.
problem	pallas::GradientProblem. The problem to optimize.
parameters	double*. The starting point for further optimization.
summary	Basinhopping::Summary*. Summary instance to store the optimization details.
