Perhaps you should try some spelling variations:
"the optimization python python programming" » "the optimization method python programming" (Expand search), "the optimization option python programming" (Expand search), "the optimization methods python programming" (Expand search), "the optimization pythons python programming" (Expand search), "the optimization piton python programming" (Expand search), "the optimization pitons python programming" (Expand search)
"coder solution and complexity from" » "code solution and complexity from" (Expand search), "copper solution and complexity from" (Expand search), "powder solution and complexity from" (Expand search), "coder evolution and complexity from" (Expand search), "coder solution _ complexity from" (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 and complexity from\") OR (\"the optimization python python programming\"))~".
• Removing quotes may allow a broader search: (( coder solution and complexity from ) OR ( the optimization python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder solution and complexity from") OR ("the optimization python python programming"))*.
