Code implementation in this submodule applications are not very well maintained and extensively tested. There are indeed many interesting pieces, but try on your own risk.
In applications, framework and relevant applications of DQAS are implemented, mainly in vags.py and dqas.py.
The entrypoint of DQAS framework is DQAS_search and DQAS_search_pmb for advanced probabilistic model based DQAS.
One can also check examples for integrated example demos.
The main library functions and utilities are in vqes.py. Also see examples including vqnhe_h6.py and adiabatic_vqnhe.py.
