Detailed Description

Mutator is designed to mutate the trace to explore the design space.

Constructor & Destructor Documentation

◆ ~MutatorNode()

virtual tvm::meta_schedule::MutatorNode::~MutatorNode ( )

virtualdefault

Virtual destructor.

Member Function Documentation

◆ Apply()

virtual Optional<tir::Trace> tvm::meta_schedule::MutatorNode::Apply	(	const tir::Trace &	trace,
		support::LinearCongruentialEngine::TRandState *	rand_state
	)

pure virtual

Apply the mutator function to the given trace.

Parameters

trace	The given trace for mutation.
rand_state	The random state for mutation.

Returns: None if mutator failed, otherwise return the mutated trace.

Implemented in tvm::meta_schedule::PyMutatorNode.

◆ Clone()

virtual Mutator tvm::meta_schedule::MutatorNode::Clone ( ) const

pure virtual

Clone the mutator.

Returns: The cloned mutator.

Implemented in tvm::meta_schedule::PyMutatorNode.

◆ InitializeWithTuneContext()

virtual void tvm::meta_schedule::MutatorNode::InitializeWithTuneContext ( const TuneContext & context )

pure virtual

Initialize the design space generator with tuning context.

Parameters

context The tuning context for initialization.

Note: This method is supposed to be called only once before every other method.

Implemented in tvm::meta_schedule::PyMutatorNode.

◆ TVM_DECLARE_BASE_OBJECT_INFO()

tvm::meta_schedule::MutatorNode::TVM_DECLARE_BASE_OBJECT_INFO	(	MutatorNode	,
		Object
	)

◆ VisitAttrs()

void tvm::meta_schedule::MutatorNode::VisitAttrs ( tvm::AttrVisitor * v )

inline
