Detailed Description

Classes for defining optimization problems.

Classes
class	BoxConstrProblem< Conf >
	Implements common problem functions for minimization problems with box constraints. More...
class	FunctionalProblem< Conf >
	Problem class that allows specifying the basic functions as C++ std::functions. More...
class	TypeErasedControlProblem< Conf, Allocator >
	Nonlinear optimal control problem with finite horizon \( N \). More...
struct	ProblemWithCounters< Problem >
	Problem wrapper that keeps track of the number of evaluations and the run time of each function. More...
class	TypeErasedProblem< Conf, Allocator >
	The main polymorphic minimization problem interface. More...
class	UnconstrProblem< Conf >
	Implements common problem functions for minimization problems without constraints. More...
class	CasADiProblem< Conf >
	Problem definition for a CasADi problem, loaded from a DLL. More...
class	CUTEstProblem
	Wrapper for CUTEst problems loaded from an external shared library. More...

Functions
template<class Problem >
auto	problem_with_counters (Problem &&p)
	Wraps the given problem into a ProblemWithCounters and keeps track of how many times each function is called, and how long these calls took.
template<class Problem >
auto	problem_with_counters_ref (Problem &p)
	Wraps the given problem into a ProblemWithCounters and keeps track of how many times each function is called, and how long these calls took.
template<Config Conf>
void	print_provided_functions (std::ostream &os, const TypeErasedProblem< Conf > &problem)

Function Documentation

problem_with_counters()

template<class Problem >

auto problem_with_counters

(

Problem &&

p

)

Wraps the given problem into a ProblemWithCounters and keeps track of how many times each function is called, and how long these calls took.

The wrapper has its own copy of the given problem. Making copies of the wrapper also copies the underlying problem, but does not copy the evaluation counters, all copies share the same counters.

Definition at line 121 of file problem-with-counters.hpp.

problem_with_counters_ref()

template<class Problem >

auto problem_with_counters_ref

(

Problem &

p

)

Wraps the given problem into a ProblemWithCounters and keeps track of how many times each function is called, and how long these calls took.

The wrapper keeps only a reference to the given problem, it is the responsibility of the caller to make sure that the wrapper does not outlive the original problem. Making copies of the wrapper does not copy the evaluation counters, all copies share the same counters.

Examples

print_provided_functions()

template<Config Conf>

void print_provided_functions	(	std::ostream &	os,
