# Inline Markup¶

Paragraphs contain text and may contain inline markup: emphasis, strong emphasis, inline literals, standalone hyperlinks (http://www.python.org), external hyperlinks (Python), internal cross-references (Title), external hyperlinks with embedded URIs (Python web site), footnote references (manually numbered 1, anonymous auto-numbered 3, labeled auto-numbered 2, or symbolic *), and citation references (12). Character-level inline markup is also possible (although exceedingly ugly!) in reStructuredText. Problems are indicated by |problematic| text (generated by processing errors; this one is intentional).

# Footnotes¶

1(1,2)

A footnote contains body elements, consistently indented by at least 3 spaces.

This is the footnote’s second paragraph.

2(1,2)

Footnotes may be numbered, either manually (as in 1) or automatically using a “#”-prefixed label. This footnote has a label so it can be referred to from multiple places, both as a footnote reference (2) and as a hyperlink reference (label).

3

This footnote is numbered automatically and anonymously using a label of “#” only.

*

Footnotes may also use symbols, specified with a “*” label. Here’s a reference to the next footnote: .

This footnote shows the next symbol in the sequence.

4

Here’s an unreferenced footnote, with a reference to a nonexistent footnote: [5]_.

# Citations¶

11

This is the citation I made, let’s make this extremely long so that we can tell that it doesn’t follow the normal responsive table stuff.

12

This citation has some code blocks in it, maybe some bold and italics too. Heck, lets put a link to a meta citation 13 too.

This citation will have two backlinks.

# Math¶

This is a test. Here is an equation: $$X_{0:5} = (X_0, X_1, X_2, X_3, X_4)$$. Here is another:

(1)$\nabla^2 f = \frac{1}{r^2} \frac{\partial}{\partial r} \left( r^2 \frac{\partial f}{\partial r} \right) + \frac{1}{r^2 \sin \theta} \frac{\partial f}{\partial \theta} \left( \sin \theta \, \frac{\partial f}{\partial \theta} \right) + \frac{1}{r^2 \sin^2\theta} \frac{\partial^2 f}{\partial \phi^2}$

You can add a link to equations like the one above (1) by using :eq:.

class BinaryQuadraticModel(*args, offset: = None, vartype: = None, dtype: Union[numpy.dtype, None, type, numpy.typing._dtype_like._SupportsDType[numpy.dtype], str, Tuple[Any, int], Tuple[Any, Union[typing_extensions.SupportsIndex, Sequence[typing_extensions.SupportsIndex]]], List[Any], numpy.typing._dtype_like._DTypeDict, Tuple[Any, Any]] = None)[source]

Binary quadratic models (BQMs) are problems of the form:

$E(\bf{v}) = \sum_{i=1} a_i v_i + \sum_{i<j} b_{i,j} v_i v_j + c \qquad\qquad v_i \in\{-1,+1\} \text{ or } \{0,1\}$

where $$a_{i}, b_{ij}, c$$ are real values.

This class encodes Ising and quadratic unconstrained binary optimization (QUBO) models used by samplers such as the D-Wave system.

With one or more of the following parameters,

• vartype: The valid variable types for binary quadratic models, is one of:

• bqm: An existing BQM.

• n: Required number of variables.

• quadratic: Quadratic biases, as a dictionary of form {(u, v): b, ...} or a square array_like.

• linear: Linear biases, as a dictionary of the form {v: b, ...} or a one-dimensional array_like.

• offset: Offset as a number.

you can create BQMs in several ways:

• BinaryQuadraticModel(vartype) with no variables or interactions.

• BinaryQuadraticModel(bqm) from an existing BQM. The resulting BQM has the same variables, linear biases, quadratic biases and offset as bqm.

• BinaryQuadraticModel(bqm, vartype) from an existing BQM, changing to the specified vartype if necessary.

• BinaryQuadraticModel(n, vartype) with n variables, indexed linearly from zero, setting all biases to zero.

• BinaryQuadraticModel(quadratic, vartype) from quadratic biases. When formed with SPIN-variables, biases on the diagonal are added to the offset.

• BinaryQuadraticModel(linear, quadratic, vartype) from linear and quadratic biases.

• BinaryQuadraticModel(linear, quadratic, offset, vartype) from linear and quadratic biases and an offset.

Parameters
• *args – See above.

• offset – Offset (see above) may be supplied as a keyword argument.

• vartype – Variable type (see above) may be supplied as a keyword argument.

• dtype – Data type. numpy.float32 and numpy.float64 are supported. Defaults to numpy.float64.

## Methods/Attributes¶

 num_variables Number of variables in the model. get_linear(v) Get the linear bias of a variable.
