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 with varying program" » "coder solution with drying programs" (Expand search), "code solution with varying program" (Expand search), "powder solution with varying program" (Expand search), "copper solution with varying program" (Expand search), "coder solutions with varying program" (Expand search), "coder solution time varying 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 with varying program\") OR (\"and optimization python python programming\"))~".
• Removing quotes may allow a broader search: (( coder solution with varying program ) OR ( and optimization python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder solution with varying program") OR ("and optimization python python programming"))*.
