"Orquestra's library with optimization routines and interfaces"
Project description
orquestra-opt
What is it?
orquestra-opt
is a library with core functionalities for optimizing cost functions developed by Zapata for our Orquestra platform.
orquestra-opt
provides:
- interfaces for implementing ansatzes including qaoa and qcbm.
- optimizers and cost functions tailored to opt
- misc functions such as grouping, qaoa interpolation, and estimators
Installation
Even though it's intended to be used with Orquestra, orquestra-opt
can be also used as a standalone Python module.
For a basic install, you just need to run pip install -e .
from the main directory.
If you need to make use of optimizers from qiskit or solve qubo problems, then you should instead run pip install -e '.[qiskit]'
or pip install -e '.[qubo]'
respectively. If you need both, you should run pip install -e '.[all]'
Usage
Here's an example of how to use methods from orquestra-opt
to solve a simple maximum cut problem.
from orquestra.opt.problems import MaxCut
import networkx as nx
def orquestra_opt_example_function()
graph = nx.complete_graph(4)
value, solutions = MaxCut().solve_by_exhaustive_search(graph)
return solutions
Development and Contribution
You can find the development guidelines in the orquestra-quantum
repository.
