Perhaps you should try some spelling variations:
"time optimization python python programming" » "time optimization method python programming" (Expand search), "time optimization option python programming" (Expand search), "time optimization methods python programming" (Expand search), "the optimization python python programming" (Expand search), "engine optimization python python programming" (Expand search), "shape optimization python python programming" (Expand search), "time optimization pythons python programming" (Expand search), "time optimization piton python programming" (Expand search), "time optimization pitons python programming" (Expand search)
"coder solutions in coding problems" » "coder solution in coding problems" (Expand search), "holder solutions in coding problems" (Expand search), "powder solutions in coding problems" (Expand search), "coder solutions in loading problems" (Expand search), "coder solutions in counting problems" (Expand search), "coder solutions in covering problems" (Expand search), "coder solutions _ coding problems" (Expand search), "coder solutions on coding problems" (Expand search), "coder solutions in decoding problems" (Expand search), "coder solutions non coding problems" (Expand search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("coder solutions in coding problems") OR ("time optimization python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder solutions in coding problems\") OR (\"time optimization python python programming\"))*".
• Removing quotes may allow a broader search: (( coder solutions in coding problems ) OR ( time optimization python python programming ))*.
