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 instruction time coding program" » "gender instruction time coding program" (Expand search), "code d'instruction time coding program" (Expand search), "peer instruction time coding program" (Expand search), "coder instruction the coding program" (Expand search), "coder instruction in coding program" (Expand search), "coder instruction to coding program" (Expand search), "coder instruction time cloning program" (Expand search), "coder instruction time loading program" (Expand search), "coder instruction time cooling programs" (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 instruction time coding program\") OR (\"and optimization python python programming\"))~".
• Removing quotes may allow a broader search: (( coder instruction time coding program ) OR ( and optimization python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder instruction time coding program") OR ("and optimization python python programming"))*.
