Perhaps you should try some spelling variations:
"by computation _ generalized array" » "by computation _ generalized arma" (Expand search), "by computation _ generalized airy" (Expand search), "by computation _ generalized early" (Expand search), "by computational _ generalized array" (Expand search), "of computation _ generalized array" (Expand search), "_ computation _ generalized array" (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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"by computation _ generalized array\") OR (\"using python python python programming\"))~".
• Removing quotes may allow a broader search: (( by computation _ generalized array ) OR ( using python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("by computation _ generalized array") OR ("using python python python programming"))*.
