def dimensions
  @dimensions
end

#domain_as_mins_maxs ⇒ Object

For more complex domains sub-classes can override this method.

def domain_as_mins_maxs
  [domain_per_dimension] * self.dimensions
end

#domain_per_dimension ⇒ Object

Domain (min, max) per dimension. Override this (or just override search_space or domain_as_mins_maxs directly) so that a typical/valid search space can be created.

Raises:

  • (NotImplementedError)

def domain_per_dimension
  raise NotImplementedError
end

#search_space ⇒ Object

Create a valid search space. Default is to use the domain_per_dimension a dimension number of times.
