Perhaps you should try some spelling variations:
implement control » implementing control (Expand search), employment control (Expand search), movement control (Expand search)
and implement » and implements (Expand search), and complement (Expand search), and implementing (Expand search)
python python » pythons python (Expand search), piton python (Expand search), pitons python (Expand search)
model python » modulo python (Expand search), monty python (Expand search), tool python (Expand search)
using model » ising model (Expand search), using mobile (Expand search), making model (Expand search)

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( code AND implement control program ) OR ( using model python python programming ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( code and implement control program ) OR ( using model python python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( code and implement control program ) OR ( using model python python programming ))*.
