Perhaps you should try some spelling variations:
"advanced computational and computer program" » "and computational and computer program" (Expand search), "advanced computational fluid computer program" (Expand search), "advanced computational _ computer program" (Expand search)
"based computational in python programming" » "and computational in python programming" (Expand search), "by computational in python programming" (Expand search), "based computational _ python programming" (Expand search), "based computational 3d python programming" (Expand search), "based computational aids 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: (("advanced computational and computer program") OR ("based computational in python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced computational and computer program\") OR (\"based computational in python programming\"))".
• Removing quotes may allow a broader search: (( advanced computational and computer program ) OR ( based computational in python programming )).
• Adding a wildcard symbol may retrieve word variants: (("advanced computational and computer program") OR ("based computational in python programming"))*.
