Perhaps you should try some spelling variations:
"based computational in computer program" » "and computational in computer program" (Expand search), "by computational in computer program" (Expand search), "based computational and computer program" (Expand search), "based computational _ computer program" (Expand search), "based computational 3d computer program" (Expand search)
"using computational model python programming" » "and computational model python programming" (Expand search), "using computational modeling python programming" (Expand search), "using computational modulo python programming" (Expand search), "using computational monty python programming" (Expand search), "using computational tool 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 in computer program") OR ("using computational model python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computational in computer program\") OR (\"using computational model python programming\"))*".
• Removing quotes may allow a broader search: (( based computational in computer program ) OR ( using computational model python programming ))*.
