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