Perhaps you should try some spelling variations:
"using computational algorithm based array" » "using computational algorithms based array" (Expand search), "and computational algorithm based array" (Expand search), "using computational algorithm phased array" (Expand search), "using computational algorithm based spray" (Expand search), "using computational algorithm phased arrays" (Expand search)
"using in python python programming" » "using in pythons python programming" (Expand search), "using in piton python programming" (Expand search), "using in pitons python programming" (Expand search), "using _ 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: (("using computational algorithm based array") OR ("using in python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"using computational algorithm based array\") OR (\"using in python python programming\"))*".
• Removing quotes may allow a broader search: (( using computational algorithm based array ) OR ( using in python python programming ))*.
