Perhaps you should try some spelling variations:
"based computations using external programming" » "based computations using paternal programming" (Expand search), "based computations using maternal programming" (Expand search), "based computations using interval programming" (Expand search), "based computation using external programming" (Expand search), "based computational using external programming" (Expand search), "based competition using external programming" (Expand search), "based populations using external programming" (Expand search), "based computations in external programming" (Expand search)
"using python python python programming" » "using pythons python python programming" (Expand search), "using piton python python programming" (Expand search), "using pitons python python programming" (Expand search), "usando python python python programming" (Expand search), "in python 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: "((\"based computations using external programming\") OR (\"using python python python programming\"))~".
• Removing quotes may allow a broader search: (( based computations using external programming ) OR ( using python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computations using external programming") OR ("using python python python programming"))*.
