Perhaps you should try some spelling variations:
"and optimization python python programming" » "and optimization method python programming" (Expand search), "and optimization option python programming" (Expand search), "and optimization methods python programming" (Expand search), "and optimization pythons python programming" (Expand search), "and optimization piton python programming" (Expand search), "and optimization pitons python programming" (Expand search)
"and controllers using coding program" » "and controller tuning coding program" (Expand search), "and controllers in coding program" (Expand search), "and control using coding program" (Expand search), "and controller using coding program" (Expand search), "pid controllers using coding program" (Expand search), "and controlled using coding program" (Expand search), "and controllers using cloning program" (Expand search), "and controllers using loading program" (Expand search), "and controllers using cooling programs" (Expand search), "and controllers using coping program" (Expand search), "and controllers using coating program" (Expand search), "and controllers using cooking program" (Expand search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"and controllers using coding program\") OR (\"and optimization python python programming\"))~".
• Removing quotes may allow a broader search: (( and controllers using coding program ) OR ( and optimization python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and controllers using coding program") OR ("and optimization python python programming"))*.
