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)
"coder function sampling using program" » "coder suction sampling using program" (Expand search), "coder function mapping using program" (Expand search), "coder function sample using program" (Expand search), "modern function sampling using program" (Expand search), "power function sampling using program" (Expand search), "over function sampling using program" (Expand search), "coder function samples using program" (Expand search), "coder function sampling in program" (Expand search), "coder function sampling unit program" (Expand search), "coder function sampling housing program" (Expand search), "coder function sampling nursing program" (Expand search), "coder function sampling aging 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: (("coder function sampling using program") OR ("and optimization python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder function sampling using program\") OR (\"and optimization python python programming\"))".
• Removing quotes may allow a broader search: (( coder function sampling using program ) OR ( and optimization python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("coder function sampling using program") OR ("and optimization python python programming"))*.
