Classes
struct	CompleteExperiment
	This structure holds experimental data for a set of planners. More...

struct	PlannerExperiment
	The data collected after running a planner multiple times. More...

struct	Request
	Representation of a benchmark request. More...

struct	Status
	This structure contains information about the activity of a benchmark instance. If the instance is running, it is possible to find out information such as which planner is currently being tested or how much. More...

Public Types
using	RunProperties = std::map< std::string, std::string >
	The data collected from a run of a planner is stored as key-value pairs.

using	RunProgressData = std::vector< std::map< std::string, std::string > >

using	PreSetupEvent = std::function< void(const base::PlannerPtr &)>
	Signature of function that can be called before a planner execution is started.

using	PostSetupEvent = std::function< void(const base::PlannerPtr &, RunProperties &)>
	Signature of function that can be called after a planner execution is completed.

Public Member Functions
	Benchmark (geometric::SimpleSetup &setup, const std::string &name=std::string())
	Constructor needs the SimpleSetup instance needed for planning. Optionally, the experiment name (name) can be specified.

	Benchmark (control::SimpleSetup &setup, const std::string &name=std::string())
	Constructor needs the SimpleSetup instance needed for planning. Optionally, the experiment name (name) can be specified.

void	addExperimentParameter (const std::string &name, const std::string &type, const std::string &value)
	Add an optional parameter's information to the benchmark output. Useful for aggregating results over different benchmark instances, e.g., parameter sweep. type is typically "BOOLEAN", "INTEGER", or "REAL".

const std::map< std::string, std::string > &	getExperimentParameters () const
	Get all optional benchmark parameters. The map key is 'name type'

std::size_t	numExperimentParameters () const
	Return the number of optional benchmark parameters.

void	setExperimentName (const std::string &name)
	Set the name of the experiment.

const std::string &	getExperimentName () const
	Get the name of the experiment.

void	addPlanner (const base::PlannerPtr &planner)
	Add a planner to use.

void	addPlannerAllocator (const base::PlannerAllocator &pa)
	Add a planner allocator to use.

void	clearPlanners ()
	Clear the set of planners to be benchmarked.

void	setPlannerSwitchEvent (const PreSetupEvent &event)
	Set the event to be called before any runs of a particular planner (when the planner is switched)

void	setPreRunEvent (const PreSetupEvent &event)
	Set the event to be called before the run of a planner.

void	setPostRunEvent (const PostSetupEvent &event)
	Set the event to be called after the run of a planner.

virtual void	benchmark (const Request &req)
	Benchmark the added planners on the defined problem. Repeated calls clear previously gathered data. More...

const Status &	getStatus () const
	Get the status of the benchmarking code. This function can be called in a separate thread to check how much progress has been made.

const CompleteExperiment &	getRecordedExperimentData () const
	Return all the experiment data that would be written to the results file. The data should not be changed, but it could be useful to quickly extract cartain statistics.

virtual bool	saveResultsToStream (std::ostream &out=std::cout) const
	Save the results of the benchmark to a stream.

bool	saveResultsToFile (const char *filename) const
	Save the results of the benchmark to a file.

bool	saveResultsToFile () const
	Save the results of the benchmark to a file. The name of the file is the current date and time.

Protected Attributes
geometric::SimpleSetup *	gsetup_
	The instance of the problem to benchmark (if geometric planning)

control::SimpleSetup *	csetup_
	The instance of the problem to benchmark (if planning with controls)

std::vector< base::PlannerPtr >	planners_
	The set of planners to be tested.

CompleteExperiment	exp_
	The collected experimental data (for all planners)

Status	status_
	The current status of this benchmarking instance.

PreSetupEvent	plannerSwitch_
	Event to be called when the evaluated planner is switched.

PreSetupEvent	preRun_
	Event to be called before the run of a planner.

PostSetupEvent	postRun_

void ompl::tools::Benchmark::benchmark ( const Request & req )

virtual

Benchmark the added planners on the defined problem. Repeated calls clear previously gathered data.

Parameters

req	The parameters for the execution of the benchmark

Note: The values returned for memory consumption may be misleading. Memory allocators often free memory in a lazy fashion, so the returned values for memory consumption indicate the increase in memory usage for each run. Since not all the memory for the previous run was freed, the increase in usage may be close to 0. To get correct averages for memory usage, use req.runCount = 1 and run the process multiple times.
