Perhaps you should try some spelling variations:
"based computational in inverse problem" » "and computational in inverse problem" (Expand search), "by computational in inverse problem" (Expand search), "based computational and inverse problem" (Expand search), "based computational _ inverse problem" (Expand search), "based computational 3d inverse problem" (Expand search), "based computational an inverse problem" (Expand search), "based computational of inverse problem" (Expand search)
"using python python python programming" » "using pythons python python programming" (Expand search), "using piton python python programming" (Expand search), "using pitons python python programming" (Expand search), "usando python python python programming" (Expand search), "in python python 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 inverse problem") OR ("using python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computational in inverse problem\") OR (\"using python python python programming\"))".
• Removing quotes may allow a broader search: (( based computational in inverse problem ) OR ( using python python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("based computational in inverse problem") OR ("using python python python programming"))*.
