|
Evaluates the Einstein summation convention on the operands. |
|
Find a contraction order ‘path’, without performing the contraction. |
|
Generate a reusable expression for a given contraction with specific shapes, which can, for example, be cached. |
Helper class for storing an explicit |
|
A printable object to contain information about a contraction path. |
|
|
Computes all possible pair contractions in a depth-first recursive manner, sieving results based on |
|
Finds the path by a three stage algorithm: |

|
Get the symbol corresponding to int |
|
Context in which contract intermediate results are shared. |
|
Base class for different path optimizers to inherit from. |
|
|
Explores possible pair contractions in a depth-first recursive manner like the |
Base class for running any random path finder that benefits from repeated calling, possibly in a parallel fashion. |
|
|
|
Finds the optimal path of pairwise contractions without intermediate outer products based a dynamic programming approach presented in Phys. |
