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