Perhaps you should try some spelling variations:
"based computational xcode java programming" » "and computational xcode java programming" (Expand search), "by computational xcode java programming" (Expand search), "based computational code java programming" (Expand search), "based computational codes java programming" (Expand search), "based computational mode java programming" (Expand search), "based computational xcode and programming" (Expand search), "based computational xcode based programming" (Expand search), "based computational xcode goal programming" (Expand search)
"using vis python python programming" » "using vis pythons python programming" (Expand search), "using vis piton python programming" (Expand search), "using vis pitons python programming" (Expand search), "using via python python programming" (Expand search), "using in python python programming" (Expand search), "using lib python python programming" (Expand search), "using visual 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: (("based computational xcode java programming") OR ("using vis python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computational xcode java programming\") OR (\"using vis python python programming\"))".
• Removing quotes may allow a broader search: (( based computational xcode java programming ) OR ( using vis python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("based computational xcode java programming") OR ("using vis python python programming"))*.
