def get_params(cost, criterion=lambda x: hasattr(x, 'param') and x.param==True):
    """
    Default criterion:
        lambda x: hasattr(x, 'param') and x.param==True
    This will return every parameter for cost from computation graph.

    To exclude a parameter, just set 'param' to False:
        >>> h0 = lib.param('h0',\
                numpy.zeros((3, 2*512), dtype=theano.config.floatX))
        >>> print h0.param  # Default: True
        >>> h0.param = False

    In this case one still can get list of all params (False or True) by:
        >>> lib.get_params(cost, lambda x: hasattr(x, 'param')

    :returns:
        A list of params

    return search(cost, criterion)
