Perhaps you should try some spelling variations:
"by computational and computational program" » "by computational fluid computational program" (Expand search), "by computational _ computational program" (Expand search), "_ computational and computational program" (Expand search)
"using computational on python programming" » "using computational one python programming" (Expand search), "using computacional on python programming" (Expand search), "using computational _ python programming" (Expand search), "using computational in python programming" (Expand search), "using computational of 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: (("by computational and computational program") OR ("using computational on python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"by computational and computational program\") OR (\"using computational on python programming\"))".
• Removing quotes may allow a broader search: (( by computational and computational program ) OR ( using computational on python programming )).
• Adding a wildcard symbol may retrieve word variants: (("by computational and computational program") OR ("using computational on python programming"))*.
