Instance Methods

[hide private]

__init__(self, bounds)
bounds are not copied, but possibly modified and put into a normalized form: bounds can be None or [lb, ub] where lb and ub are either None or a vector (which can have None entries). source code

__call__(self, solutions, *args, **kwargs)
return penalty or list of penalties, by default zero(s).

source code

update(self, *args, **kwargs)

source code

repair(self, x, copy_if_changed=True, copy_always=False)
projects infeasible values on the domain bound, might be overwritten by derived class

source code

inverse(self, y, copy_if_changed=True, copy_always=False)

source code

get_bounds(self, which, dimension)
get_bounds('lower', 8) returns the lower bounds in 8-D source code

_get_bounds(self, ib, dimension)
ib == 0/1 means lower/upper bound, return a vector of length dimension source code

has_bounds(self)
return True, if any variable is bounded

source code

is_in_bounds(self, x)
not yet tested

source code

to_dim_times_two(self, bounds)
return boundaries in format [[lb0, ub0], [lb1, ub1], ...], as used by BoxConstraints... class. source code

Method Details

[hide private]

init(self, bounds)
(Constructor)

source code

bounds are not copied, but possibly modified and put into a normalized form: bounds can be None or [lb, ub] where lb and ub are either None or a vector (which can have None entries).

Generally, the last entry is recycled to compute bounds for any dimension.

Overrides: object.__init__

call(self, solutions, *args, **kwargs)
(Call operator)

source code

return penalty or list of penalties, by default zero(s).

This interface seems too specifically tailored to the derived BoundPenalty class, it should maybe change.
