Array-valued \n        integrands are useful for integrands that \n        are closely related, and can lead to \n        substantial reductions in the errors for \n        ratios or differences of the results.\n\n        It is usually much faster to use |vegas| in batch\n        mode, where integration points are presented to the \n        integrand in batches. A simple batch integrand might\n        be, for example::\n\n            @vegas.batchintegrand \n            def f(x):\n                return x[:, 0] ** 2 + x[:, 1] ** 4\n\n        where decorator ``@vegas.batchintegrand`` tells \n        |vegas| that the integrand processes integration\n        points in batches. The array ``x[i, d]`` \n        represents a collection of different integration \n        points labeled by ``i=0...``. (The number of points is controlled\n        |Integrator| parameter ``nhcube_batch``.) The batch index \n        is always first.\n\n        Batch integrands can also be constructed from classes \n        derived from :class:`vegas.BatchIntegrand`.\n    \n        Batch mode is particularly useful (and fast) when the class \n        derived from :class:`vegas.BatchIntegrand` is coded \n        in Cython. Then loops over the integration points\n        can be coded explicitly, avoiding the need to use\n        :mod:`numpy`'s whole-array operators if they are not \n        well suited to the integrand.\n\n        Any |vegas| parameter can also be reset: e.g., ""\n        ``self(fcn, nitn=20, neval=1e6)``.\n        ";

  __Pyx_DOCSTR(" Adaptive multidimensional Monte Carlo integration.\n\n    :class:`vegas.Integrator` objects make Monte Carlo \n    estimates of multidimensional functions ``f(x)``\n    where ``x[d]`` is a point in the integration volume::\n\n        integ = vegas.Integrator(integration_region)\n\n        result = integ(f, nitn=10, neval=10000)\n\n    The integator makes ``nitn`` estimates of the integral,  each\n    using at most ``neval`` samples of the integrand, as it adapts to\n    the specific features of the integrand. Successive estimates (iterations)\n    typically improve in accuracy until the integrator has fully\n    adapted. The integrator returns the weighted average of all\n    ``nitn`` estimates, together with an estimate of the statistical\n    (Monte Carlo) uncertainty in that estimate of the integral. The\n    result is an object of type :class:`RAvg` (which is derived\n    from :class:`gvar.GVar`).\n\n    Integrands can be array-valued, in which case ``f(x)`` \n    returns an array of values corresponding to different \n    integrands. Also |vegas| can generate integration points\n    in batches for integrands built from classes\n    derived from :class:`vegas.BatchIntegrand`, or integrand\n    functions decorated by :func:`vegas.batchintegrand`. Batch \n    integrands are typically much faster, especially if they\n    are coded in Cython.\n\n    |Integrator|\\s have a large number of parameters but the \n    only ones that most people will care about are: the\n    number ``nitn`` of iterations of the |vegas| algorithm;\n    the maximum number ``neval`` of integrand evaluations per\n    iteration; and the damping parameter ``alpha``, which is used\n    to slow down the adaptive algorithms when they would otherwise\n    be unstable (e.g., with very peaky integrands). Setting parameter\n    ``analyzer=vegas.reporter()`` is sometimes useful, as well,\n    since it causes |vegas| to print (on ``sys.stdout``) \n    intermediate results from each iteration, as they are \n    produced. This helps when each iteration takes a long time \n    to complete (e.g., an hour) because it allows you to \n    monitor progress as it is being made (or not).\n\n    :param map: The integration region as specified by \n        an array ``map[d, i]`` where ``d`` is the \n        direction and ``i=0,1`` specify the lower\n        and upper limits of integration in direction ``d``.\n\n        ``map`` could also be the integration map from \n        another |Integrator|, or that |Integrator|\n        itself. In this case the grid is copied from the \n        existing integrator.\n    :type map: array or :class:`vegas.AdaptiveMap` \n        or :class:`vegas.Integrator`\n    :param nitn: The maximum number of iterations used to \n        adapt to the integrand and estimate its value. The\n        default value is 10; typical values range from 10\n        to 20.\n    :type nitn: positive int\n    :param neval: The maximum number of integrand evaluations\n        in each iteration of the |vegas| algorithm. Increasing\n        ``neval`` increases the precision: statistical errors should\n        fall at least as fast as ``sqrt(1./neval)`` and often\n        fall much faster. The default value is 1000; real\n        problems often require 10--1000 times more evaluations\n        than this.\n    :type neval: positive int \n    :param alpha: Damping parameter controlling the remapping\n        of the integration variables as |vegas| adapts to the\n        integrand. Smaller values slow adaptation, which may be\n        desirable for difficult integrands. Small or zero ``alpha``\\s \n        are also sometimes useful after the grid has adapted,\n        to minimize fluctuations away from the optimal grid.\n        The default value is 0.5.\n    :type alpha: float \n    :param beta: Damping parameter controlling the redistribution\n        of integrand evaluations across hypercubes in the \n        stratified sampling of the integral (over transformed\n        variables). Smaller values limit the amount of \n        redistribution. The theoretically optimal value is 1;\n        setting ``beta=0`` prevents any redistribution of \n        evaluations. The default value is 0.75.\n    :type beta: float \n    :param adapt: Setting ``adapt=False`` prevents further \n        adaptation by |vegas|. Typically this would be done \n        after training the |Integrator| on an integrand, in order\n        to stabilize further estimates of the integral. |vegas| uses \n        unweighted averages to combine results from different \n        iterations when ``adapt=False``. The default setting \n        is ``adapt=True``.\n    :type adapt: bool\n    :param nhcube_batch: The number of hypercubes (in |y| space)\n        whose integration points are combined into a single\n        batch to be passed to the integrand, together,\n        when using |vegas| in batch mode.\n        The default value is 1000. Larger values may be\n        lead to faster evaluations, but at the cost of \n        more memory for internal work arrays.\n    :type nhcube_batch: positive int \n    :param minimize_mem: When ``True``, |vegas| minimizes \n        internal workspace at the cost of extra evaluations of\n        the integrand. This can increase execution time by \n        50--100% but might be desirable when the number of \n        evaluations is very large (e.g., ``neval=1e9``). Normally\n        |vegas| uses internal work space that grows in \n        proportion to ``neval``. If that work space exceeds\n        the size of the RAM available to the processor,\n        |vegas| runs much more slowly. Setting ``minimize_mem=True``\n        greatly reduces the internal storage used by |vegas|; in \n        particular memory becomes independent of ``neval``. The default\n        setting (``minimize_mem=False``), however, is much superior \n        unless memory becomes a problem. (The large memory is needed \n        for adaptive stratified sampling, so memory is not \n        an issue if ``beta=0``.)\n    :type minimize_mem: bool\n    :param adapt_to_errors: ``adapt_to_errors=False`` causes \n        |vegas| to remap the integration variables to emphasize\n        regions where ``|f(x)|`` is largest. This is \n        the default mode.\n\n        ``adapt_to_errors=True`` causes |vegas| to remap \n        variables to emphasize regions where the Monte Carlo\n        error is largest. This might be superior when \n        the number of the number of stratifications (``self.nstrat``)\n        in the |y| grid is large (> 50?). It is typically \n        useful only in one or two dimensions.\n    :type adapt_to_errors: bool\n    :param maxinc_axis: The maximum number of increments\n        per axis allowed for the |x|-space grid. The default \n        value is 1000; there is probably little need to use\n        other values.\n    :type maxinc_axis: positive int \n    :param max_nhcube: Maximum number of |y|-space hypercubes \n        used for stratified sampling. Setting ``max_nhcube=1``\n        turns stratified sampling off, which is probably never \n        a good idea. The default setting (1e9) was chosen to \n        correspond to the point where internal work arrays \n        become comparable in size to the typical amount of RAM \n        available to a processor (in a laptop in 2014). \n        Internal memory usage is large only when ``beta>0``\n        and ``minimize_mem=False``; therefore ``max_nhcube`` is \n        ignored if ``beta=0`` or ``minimize_mem=True``.\n    :type max_nhcube: positive int \n    :param max_neval_hcube: Maximum number of integrand evaluations \n        per hypercube in the stratification. The default value \n        is 1e7. Larger values might allow for more adaptation\n        (when ``neval`` is larger than ``2 * max_neval_hcube``),\n        but also can result in very large internal work arrays.\n    :type max_neval_hcube: positive int\n    :param rtol: Relative error in the integral estimate \n        at which point the integrator can stop. The default\n        value is 0.0 which means that the integrator will\n        complete all iterations specified by ``nitn``.\n    :type rtol: float less than 1\n    :param atol: Absolute error in the integral estimate \n        at which point the integrator can stop. The default\n        value is 0.0 which means that the integrator will\n        complete all iterations specified by ``nitn``.\n    :type atol: float \n    :param analyzer: An object with methods \n\n            ``analyzer.begin(itn, integrator)``\n\n            ``analyzer.end(itn_result, result)``\n\n        where: ``begin(itn, integrator)`` is called at the start\n        of each |vegas| iteration with ``itn`` equal to the \n        iteration number and ``integrator`` equal to the \n        integrator itself; and ``end(itn_result, result)``\n        is called at the end of each iteration with \n        ``itn_result`` equal to the result for that \n        iteration and ``result`` equal to the cummulative\n        result of all iterations so far. \n        Setting ``analyzer=vegas.reporter()``, for \n        example, causes vegas to print out a running report\n        of its results as they are produced. The default \n        is ``analyzer=None``.\n    :param ran_array_generator: Function that generates \n        :mod:`numpy` arrays of random numbers distributed uniformly \n        between 0 and 1. ``ran_array_generator(shape)`` should \n        create an array whose dimensions are specified by the \n        integer-valued tuple ``shape``. The default generator\n        is ``ran_array_generator=numpy.random.random``.\n    "), /*tp_doc*/

  __Pyx_DOCSTR(" Adaptive map ``y->x(y)`` for multidimensional ``y`` and ``x``.\n\n    An :class:`AdaptiveMap` defines a multidimensional map ``y -> x(y)`` \n    from the unit hypercube, with ``0 <= y[d] <= 1``, to an arbitrary\n    hypercube in ``x`` space. Each direction is mapped independently \n    with a Jacobian that is tunable (i.e., \"adaptive\").\n\n    The map is specified by a grid in ``x``-space that, by definition, \n    maps into a uniformly spaced grid in ``y``-space. The nodes of \n    the grid are specified by ``grid[d, i]`` where d is the \n    direction (``d=0,1...dim-1``) and ``i`` labels the grid point\n    (``i=0,1...N``). The mapping for a specific point ``y`` into\n    ``x`` space is:: \n\n        y[d] -> x[d] = grid[d, i(y[d])] + inc[d, i(y[d])] * delta(y[d])\n\n    where ``i(y)=floor(y*N``), ``delta(y)=y*N - i(y)``, and\n    ``inc[d, i] = grid[d, i+1] - grid[d, i]``. The Jacobian for this map, :: \n\n        dx[d]/dy[d] = inc[d, i(y[d])] * N,\n\n    is piece-wise constant and proportional to the ``x``-space grid \n    spacing. Each increment in the ``x``-space grid maps into an increment of \n    size ``1/N`` in the corresponding ``y`` space. So regions in \n    ``x`` space where ``inc[d, i]`` is small are stretched out\n    in ``y`` space, while larger increments are compressed.\n\n    The ``x`` grid for an :class:`AdaptiveMap` can be specified explicitly\n    when the map is created: for example, ::\n\n        m = AdaptiveMap([[0, 0.1, 1], [-1, 0, 1]])\n\n    creates a two-dimensional map where the ``x[0]`` interval ``(0,0.1)``\n    and ``(0.1,1)`` map into the ``y[0]`` intervals ``(0,0.5)`` and \n    ``(0.5,1)`` respectively, while ``x[1]`` intervals ``(-1,0)`` \n    and ``(0,1)`` map into ``y[1]`` intervals ``(0,0.5)`` and  ``(0.5,1)``.\n\n    More typically an initially uniform map is trained with data \n    ``f[j]`` corresponding to ``ny`` points ``y[j, d]``,\n    with ``j=0...ny-1``, uniformly distributed in |y| space: \n    for example, ::\n\n        m.add_training_data(y, f)\n        m.adapt(alpha=1.5)\n\n    ``m.adapt(alpha=1.5)`` shrinks grid increments where ``f[j]``\n    is large, and expands them where ``f[j]`` is small. Typically \n    one has to iterate over several sets of ``y``\\s and ``f``\\s \n    before the grid has fully adapted. \n\n    The speed with which the grid adapts is determined by parameter ``alpha``.\n    Large (positive) values imply rapid adaptation, while small values (much\n    less than one) imply slow adaptation. As in any iterative process, it is\n    usually a good idea to slow adaptation down in order to avoid\n    instabilities.\n\n    :param grid: Initial ``x`` grid, where ``grid[d, i]`` is the ``i``-th \n        node in direction ``d``.\n    :type x: 2-d array of floats\n    :param ninc: Number of increments along each axis of the ``x`` grid. \n        A new grid is generated if ``ninc`` differs from ``grid.shape[1]``.\n        The new grid is designed to give the same Jacobian ``dx(y)/dy``\n        as the original grid. The default value, ``ninc=None``,  leaves \n        the grid unchanged.\n    :type ninc: ``int`` or ``None``\n    "), /*tp_doc*/
