Perhaps you should try some spelling variations:
"coder coding _ algorithms optimization" » "coder coding _ algorithm optimization" (Expand search), "coder coding _ algorithms simulation" (Expand search), "coder coding _ algorithms application" (Expand search), "modern coding _ algorithms optimization" (Expand search), "color coding _ algorithms optimization" (Expand search), "odor coding _ algorithms optimization" (Expand search)
"api in python python programming" » "api in pythons python programming" (Expand search), "api in piton python programming" (Expand search), "api in pitons python programming" (Expand search), "api _ python python programming" (Expand search), "api an python python programming" (Expand search), "fpi in python python programming" (Expand search), "gpi in python python programming" (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 coding _ algorithms optimization") OR ("api in python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder coding _ algorithms optimization\") OR (\"api in python python programming\"))".
• Removing quotes may allow a broader search: (( coder coding _ algorithms optimization ) OR ( api in python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("coder coding _ algorithms optimization") OR ("api in python python programming"))*.
