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)
"based controller source coding program" » "based controlled source coding program" (Expand search), "based controller sobre coding program" (Expand search), "based controller force coding program" (Expand search), "based control source coding program" (Expand search), "pid controller source coding program" (Expand search), "can controller source coding program" (Expand search), "based controller source cloning program" (Expand search), "based controller source loading program" (Expand search), "based controller source cooling programs" (Expand search), "based controller source routing program" (Expand search), "based controller source code program" (Expand search), "based controller source codes program" (Expand search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("based controller source coding program") OR ("and optimization python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based controller source coding program\") OR (\"and optimization python python programming\"))".
• Removing quotes may allow a broader search: (( based controller source coding program ) OR ( and optimization python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("based controller source coding program") OR ("and optimization python python programming"))*.
