Perhaps you should try some spelling variations:
"coder computational complexity to program" » "code computational complexity to program" (Expand search), "poder computacional complexity to program" (Expand search), "model computational complexity to program" (Expand search), "coder computational complexity the program" (Expand search), "coder computational complexity _ program" (Expand search), "coder computational complexity an program" (Expand search)
"using in python python programming" » "using in pythons python programming" (Expand search), "using in piton python programming" (Expand search), "using in pitons python programming" (Expand search), "using _ python python programming" (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 computational complexity to program\") OR (\"using in python python programming\"))~".
• Removing quotes may allow a broader search: (( coder computational complexity to program ) OR ( using in python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder computational complexity to program") OR ("using in python python programming"))*.
