ParametersReturns
_flop_count(idx_contraction, inner, num_terms, size_dictionary)

Parameters

idx_contraction : iterable

The indices involved in the contraction

inner : bool

Does this contraction require an inner product?

num_terms : int

The number of terms in a contraction

size_dictionary : dict

The size of each of the indices in idx_contraction

Returns

flop_count : int

The total number of FLOPS required for the contraction.

Computes the number of FLOPS in the contraction.

Examples

>>> _flop_count('abc', False, 1, {'a': 2, 'b':3, 'c':5})
30
>>> _flop_count('abc', True, 2, {'a': 2, 'b':3, 'c':5})
60

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
