Public Functions

template<typename T = Value, typename P = double>
inline ParamExpr tune(std::string name, std::vector<T> values, std::vector<P> priors, Value default_value)

Add a new parameter to the configuration space.

Parameters:

  • name – The name of the parameter.

  • values – The values of this parameter.

  • priors – The prior probabilities of the given values.

  • default_value – The default value that will be return by ConfigSpace::default_config().

template<typename T = Value, typename P = double>
inline ParamExpr tune(std::string name, std::vector<T> values, std::vector<P> priors)

Add a new parameter to the configuration space. The default value is assume to be the first value in the list.

Parameters:

  • name – The name of the parameter.

  • values – The values of this parameter.

  • priors – The prior probabilities of the given values.

template<typename T = Value>
inline ParamExpr tune(std::string name, std::vector<T> values, Value default_value)

Add a new parameter to the configuration space.

Parameters:

  • name – The name of the parameter.

  • values – The values of this parameter.

  • default_value – The default value that will be return by ConfigSpace::default_config().

template<typename T = Value>
inline ParamExpr tune(std::string name, std::vector<T> values)

Add a new parameter to the configuration space. The default value is assume to be the first value in the list.

Parameters:

  • name – The name of the parameter.

  • values – The values of this parameter.

inline ParamExpr operator[](const std::string &name) const

Returns the parameter expression with the given name.

inline const std::vector<TunableParam> &parameters() const

Returns the parameters of this configuration space.

void restriction(TypedExpr<bool> e)

Add a restriction to this configuration space. A configuration is only considered valid if this expression yields true.

Config default_config() const

Returns the default configuration for this configuration space.

bool is_valid(const Eval &config) const

Check if the given configuration is a valid member of this configuration space. This method essentially checks three things:

  • Does the configuration contain the correct parameters.

  • Do these parameter contain valid values.

  • Does the configuration meet the restrictions.
