Types

type GoptunaSolver

type GoptunaSolver struct {
	// contains filtered or unexported fields
}

GoptunaSolver is a Solver implementation based on Goptuna.

func (*GoptunaSolver) Ask

func (r *GoptunaSolver) Ask(idg *kurobako.TrialIDGenerator) (kurobako.NextTrial, error)

func (*GoptunaSolver) Tell

func (r *GoptunaSolver) Tell(trial kurobako.EvaluatedTrial) error

type GoptunaSolverFactory

type GoptunaSolverFactory struct {
	// contains filtered or unexported fields
}

GoptunaSolverFactory is a SolverFactory for Goptuna.

func NewGoptunaSolverFactory

func NewGoptunaSolverFactory(name string, createStudy func(int64) (*goptuna.Study, error)) GoptunaSolverFactory

NewGoptunaSolverFactory creates a new GoptunaSolverFactory instance.

The createStudy argument is a function that takes a random seed and returns a study object that is used to solve black-box optimization problems.

func (*GoptunaSolverFactory) CreateSolver

func (r *GoptunaSolverFactory) CreateSolver(seed int64, problem kurobako.ProblemSpec) (kurobako.Solver, error)

func (*GoptunaSolverFactory) Specification

func (r *GoptunaSolverFactory) Specification() (*kurobako.SolverSpec, error)
