Perhaps you should try some spelling variations:
"coder computational complexity del programa" » "code computational complexity del programa" (Expand search), "poder computacional complexity del programa" (Expand search), "model computational complexity del programa" (Expand search), "coder computational complexity model programa" (Expand search), "coder computational complexity does programa" (Expand search), "coder computational complexity all programa" (Expand search)
"using coding python python programming" » "using codigo python python programming" (Expand search), "using codigos python python programming" (Expand search), "using using python python programming" (Expand search), "using coding pythons python programming" (Expand search), "using coding piton python programming" (Expand search), "using coding pitons python programming" (Expand search), "using coping python python programming" (Expand search), "using coating python python programming" (Expand search), "using cooking 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 del programa\") OR (\"using coding python python programming\"))~".
• Removing quotes may allow a broader search: (( coder computational complexity del programa ) OR ( using coding python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder computational complexity del programa") OR ("using coding python python programming"))*.
