cma.constraints_handler.BoundTransform

class documentation

class BoundTransform(_BoundTransform):

Constructor: BoundTransform(*args, **kwargs)

Undocumented

Method __init__ Argument bounds can be None or bounds[0] and bounds[1] are lower and upper domain boundaries, each is either None or a scalar or a list or array of appropriate size.

Inherited from BoundTransform:

Method	`inverse`	inverse transform of `x` from the bounded domain.
Method	`repair`	transforms `x` into the bounded domain.
Method	`transform`	Undocumented
Instance Variable	`bounds_tf`	Undocumented

Inherited from BoundaryHandlerBase (via BoundTransform):

Method	`__call__`	return penalty or list of penalties, by default zero(s).
Method	`amend_bounds_for_integer_variables`	set bounds away from `at=0.5` such that
Method	`get_bound`	return lower and upper bound of variable with index `index`
Method	`get_bounds`	`get_bounds('lower', 8)` returns the lower bounds in 8-D
Method	`has_bounds`	return `True` if any variable is bounded
Method	`idx_out_of_bounds`	return index list of out-of-bound values in `x`.
Method	`into_bounds`	set out-of-bound values on bounds and return `x`.
Method	`is_in_bounds`	return `True` if `x` is in bounds.
Method	`to_dim_times_two`	return boundaries in format `[[lb0, ub0], [lb1, ub1], ...]`, as used by `BoxConstraints...` class.
Method	`update`	end-iteration callback of boundary handler (abstract/empty)
Instance Variable	`bounds`	Undocumented
Instance Variable	`use_cached_values`	default behavior as to whether to use cached values
Method	`_get_bounds`	ib == 0/1 means lower/upper bound, return a vector of length `dimension`
Instance Variable	`_bounds_dict`	saved return values of get_bounds(i, dim). Changing `self.bounds` may only be effective when this is reset.
