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 functions using computer program" » "power functions using computer program" (Expand search), "order functions using computer program" (Expand search), "colour functions using computer program" (Expand search), "coder function using computer program" (Expand search), "coder reactions using computer 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 functions using computer program\") OR (\"and optimization python python programming\"))~".
• Removing quotes may allow a broader search: (( coder functions using computer program ) OR ( and optimization python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder functions using computer program") OR ("and optimization python python programming"))*.
