class Bounds(builtins.object):

help(Bounds)

Bounds constraint on the variables.

The constraint has the general inequality form::

    lb <= x <= ub

It is possible to use equal bounds to represent an equality constraint or
infinite bounds to represent a one-sided constraint.

Parameters
----------
lb, ub : dense array_like, optional
    Lower and upper bounds on independent variables. `lb`, `ub`, and
    `keep_feasible` must be the same shape or broadcastable.
    Set components of `lb` and `ub` equal
    to fix a variable. Use ``np.inf`` with an appropriate sign to disable
    bounds on all or some variables. Note that you can mix constraints of
    different types: interval, one-sided or equality, by setting different
    components of `lb` and `ub` as necessary. Defaults to ``lb = -np.inf``
    and ``ub = np.inf`` (no bounds).
keep_feasible : dense array_like of bool, optional
    Whether to keep the constraint components feasible throughout
    iterations. Must be broadcastable with `lb` and `ub`.
    Default is False. Has no effect for equality constraints.
