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 solutions in complexity from" » "coder solution in complexity from" (Expand search), "holder solutions in complexity from" (Expand search), "powder solutions in complexity from" (Expand search), "coder solutions on complexity from" (Expand search), "coder solutions and complexity from" (Expand search), "coder solutions _ 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 solutions in complexity from\") OR (\"and optimization python python programming\"))~".
• Removing quotes may allow a broader search: (( coder solutions in complexity from ) OR ( and optimization python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder solutions in complexity from") OR ("and optimization python python programming"))*.
