Changelog

v1.3 (in development)

Improvements and changes

Parameter creation routines in .linear_ramp_from_hamiltonian() got all vectorized. (@ysinha1, gh-2)

v1.2 (October 9, 2019)

Improvements and changes

Variable names in qaoa.cost_function.py have been updated to better reflect their counterparts in qaoa.parameters.py.
Sped up cost function calls and construction for PrepareAndMeasureOnWFSim and QAOACostFunOnWFSim. For very small systems and hamiltonians WavefunctionSimulator().expectation() is still faster, than our implementation.
Added an example of using QAOA to solve a simple QUBO problem.
Sped up tests by removing all with local_qvm() context managers. You have to manually start a qvm in the background for the tests now!
Added sample_qaoa_bistrings to utilities.py

Bugfixes

Can access FourierExtendedParams.z_rotation_angles now for hamiltonians without bias terms.

v1.0-beta (September 12, 2019)
