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 solution _ decoding program" » "coder solution _ welcoming program" (Expand search), "coder solution _ deworming program" (Expand search), "coder solution _ feeding program" (Expand search), "code solution _ decoding program" (Expand search), "powder solution _ decoding program" (Expand search), "copper solution _ decoding 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: "((\"coder solution _ decoding program\") OR (\"and optimization python python programming\"))~".
• Removing quotes may allow a broader search: (( coder solution _ decoding program ) OR ( and optimization python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder solution _ decoding program") OR ("and optimization python python programming"))*.
