Perhaps you should try some spelling variations:
"and computational using fixed program" » "and computation using fixed program" (Expand search), "and computations using fixed program" (Expand search), "and computacional usinas fixed program" (Expand search), "_ computational using fixed program" (Expand search), "and computational using based program" (Expand search), "and computational using led program" (Expand search), "and computational using mixed program" (Expand search), "and computational using fiber program" (Expand search), "and computational using field program" (Expand search)
"using codigo python python programming" » "using codigo pythons python programming" (Expand search), "using codigo piton python programming" (Expand search), "using codigo pitons python programming" (Expand search), "using indigo python python programming" (Expand search), "using coding python python programming" (Expand search), "using codium 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: "((\"and computational using fixed program\") OR (\"using codigo python python programming\"))~".
• Removing quotes may allow a broader search: (( and computational using fixed program ) OR ( using codigo python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and computational using fixed program") OR ("using codigo python python programming"))*.
