Perhaps you should try some spelling variations:
model implementation » modular implementation (Expand Search), world implementation (Expand Search), time implementation (Expand Search)
proof implementation » prior implementations (Expand Search), pilot implementation (Expand Search), pre implementation (Expand Search)
python model » python code (Expand Search), python tool (Expand Search), action model (Expand Search)
python proof » method proof (Expand Search), python tool (Expand Search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( python model implementation ) OR ( python proof implementation ))~.
