Perhaps you should try some spelling variations:
optimization procedures » optimization procedure (Expand search), optimization process (Expand search), estimation procedures (Expand search)
decrease optimization » release optimization (Expand search), discrete optimization (Expand search), case optimization (Expand search)
python python » pythons python (Expand search), piton python (Expand search), pitons python (Expand search)
can decrease » and decrease (Expand search), can increase (Expand search), to decrease (Expand search)
python and » python based (Expand search)
and python » in python (Expand search), on python (Expand search), api python (Expand search)
code can » code an (Expand search), code ctn (Expand search), code car (Expand search)

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

• Removing quotes may allow a broader search: (( code can decrease optimization procedures ) OR ( python and python python programming ))~.
