def ask_and_eval(self, func, args=(), gradf=None, number=None, xmean=None, sigma_fac=1,
evaluations=1, aggregation=np.median, kappa=1):
"""samples `number` solutions and evaluates them on `func`, where
each solution `s` is resampled until ``self.is_feasible(s, func(s)) is True``.
Arguments
---------
`func`
objective function, ``func(x)`` returns a scalar
`args`
additional parameters for `func`
`gradf`
gradient of objective function, ``g = gradf(x, *args)``
must satisfy ``len(g) == len(x)``
`number`
number of solutions to be sampled, by default
population size ``popsize`` (AKA lambda)
`xmean`
mean for sampling the solutions, by default ``self.mean``.
`sigma_fac`
multiplier for sampling width, standard deviation, for example
to get a small perturbation of solution `xmean`
`evaluations`
number of evaluations for each sampled solution
`aggregation`
function that aggregates `evaluations` values to
as single value.
`kappa`
multiplier used for the evaluation of the solutions, in
that ``func(m + kappa*(x - m))`` is the f-value for x.
Return
------
``(X, fit)``, where
X -- list of solutions
fit -- list of respective function values
Details
-------
While ``not self.is_feasible(x, func(x))``new solutions are sampled. By
default ``self.is_feasible == cma.feasible == lambda x, f: f not in (None, np.NaN)``.
The argument to `func` can be freely modified within `func`.
Depending on the ``CMA_mirrors`` option, some solutions are not sampled
independently but as mirrors of other bad solutions. This is a simple
derandomization that can save 10-30% of the evaluations in particular
with small populations, for example on the cigar function.
Example
-------
>>> import cma
>>> x0, sigma0 = 8*[10], 1 # 8-D
>>> es = cma.CMAEvolutionStrategy(x0, sigma0)
>>> while not es.stop():
... X, fit = es.ask_and_eval(cma.fcts.elli) # handles NaN with resampling
... es.tell(X, fit) # pass on fitness values
... es.disp(20) # print every 20-th iteration
>>> print('terminated on ' + str(es.stop()))
<output omitted>
A single iteration step can be expressed in one line, such that
an entire optimization after initialization becomes
::
while not es.stop():
es.tell(*es.ask_and_eval(cma.fcts.elli))

def pack_tups(*args):
"""Pack an arbitrary set of iterables and non-iterables into tuples.
Function packs a set of inputs with arbitrary iterability into tuples.
Iterability is tested with :func:`iterable`. Non-iterable inputs
are repeated in each output tuple. Iterable inputs are expanded
uniformly across the output tuples. For consistency, all iterables must
be the same length.
The input arguments are parsed such that bare strings are treated as
**NON-ITERABLE**, through the use of a local subclass of |str| that
cripples the ``__iter__()`` method. Any strings passed are returned
in the packed tuples as standard, **ITERABLE** instances of |str|, however.
The order of the input arguments is retained within each output tuple.
No structural conversion is attempted on the arguments.
If all inputs are non-iterable, a list containing a single |tuple| will be
returned.
Parameters
----------
\*args
Arbitrary number of arbitrary mix of iterable and non-iterable
objects to be packed into tuples.
Returns
-------
tups
|list| of |tuple| --
Number of tuples returned is equal to the length of the iterables
passed in `*args`
Raises
------
~exceptions.ValueError

def make_combined_periodogram(pflist, outfile, addmethods=False):
'''This just puts all of the period-finders on a single periodogram.
This will renormalize all of the periodograms so their values lie between 0
and 1, with values lying closer to 1 being more significant. Periodograms
that give the same best periods will have their peaks line up together.
Parameters
----------
pflist : list of dict
This is a list of result dicts from any of the period-finders in
periodbase. To use your own period-finders' results here, make sure the
result dict is of the form and has at least the keys below::
{'periods': np.array of all periods searched by the period-finder,
'lspvals': np.array of periodogram power value for each period,
'bestperiod': a float value that is the period with the highest
peak in the periodogram, i.e. the most-likely actual
period,
'method': a three-letter code naming the period-finder used; must
be one of the keys in the
`astrobase.periodbase.METHODLABELS` dict,
'nbestperiods': a list of the periods corresponding to periodogram
peaks (`nbestlspvals` below) to annotate on the
periodogram plot so they can be called out
visually,
'nbestlspvals': a list of the power values associated with
periodogram peaks to annotate on the periodogram
plot so they can be called out visually; should be
the same length as `nbestperiods` above,
'kwargs': dict of kwargs passed to your own period-finder function}
outfile : str
This is the output file to write the output to. NOTE: EPS/PS won't work
because we use alpha transparency to better distinguish between the
various periodograms.
addmethods : bool
If this is True, will add all of the normalized periodograms together,
then renormalize them to between 0 and 1. In this way, if all of the
period-finders agree on something, it'll stand out easily. FIXME:
implement this kwarg.
Returns
-------
str
The name of the generated plot file.

Parameters
----------
diagrams: ndarray (n_pairs, 2) or list of diagrams
A diagram or list of diagrams. If diagram is a list of diagrams,
then plot all on the same plot using different colors.
plot_only: list of numeric
If specified, an array of only the diagrams that should be plotted.
title: string, default is None
If title is defined, add it as title of the plot.
xy_range: list of numeric [xmin, xmax, ymin, ymax]
User provided range of axes. This is useful for comparing
multiple persistence diagrams.
labels: string or list of strings
Legend labels for each diagram.
If none are specified, we use H_0, H_1, H_2,... by default.
colormap: string, default is 'default'
Any of matplotlib color palettes.
Some options are 'default', 'seaborn', 'sequential'.
See all available styles with
.. code:: python
import matplotlib as mpl
print(mpl.styles.available)
size: numeric, default is 20
Pixel size of each point plotted.
ax_color: any valid matplotlib color type.
See [https://matplotlib.org/api/colors_api.html](https://matplotlib.org/api/colors_api.html) for complete API.
diagonal: bool, default is True
Plot the diagonal x=y line.
lifetime: bool, default is False. If True, diagonal is turned to False.
Plot life time of each point instead of birth and death.
Essentially, visualize (x, y-x).
legend: bool, default is True
If true, show the legend.
show: bool, default is False
Call plt.show() after plotting. If you are using self.plot() as part
of a subplot, set show=False and call plt.show() only once at the end.
