accelerate state copy in default policy #65

Closed peter1591 closed 7 years ago

peter1591 commented 7 years ago

In default policy, the state is copied, but applied with only one action

Try to use state-overlay to accelerate the copying

After implement copy-on-write on state::State, the time to copy the state occupies only 7% of the total runtime.
