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