Perhaps you should try some spelling variations:
"using computational python computer program" » "using computacional python computer program" (Expand search), "using computacional vpython computer program" (Expand search), "using computacionais python computer program" (Expand search), "and computational python computer program" (Expand search)
"based computational using sample of" » "and computational using sample of" (Expand search), "by computational using sample of" (Expand search), "based computation using sample of" (Expand search), "based computations using sample of" (Expand search), "based computacional usinas sample of" (Expand search), "based computational using samples of" (Expand search), "based computational using simple of" (Expand search), "based computational using simplex of" (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: (("using computational python computer program") OR ("based computational using sample of"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"using computational python computer program\") OR (\"based computational using sample of\"))".
• Removing quotes may allow a broader search: (( using computational python computer program ) OR ( based computational using sample of )).
• Adding a wildcard symbol may retrieve word variants: (("using computational python computer program") OR ("based computational using sample of"))*.
