Perhaps you should try some spelling variations:
"by computational and parallel programing" » "by computational and parallel programming" (Expand search), "by computational and parallel programs" (Expand search), "by computational and parallel processing" (Expand search), "by computational fluid parallel programing" (Expand search), "_ computational and parallel programing" (Expand search), "and computational and parallel programing" (Expand search), "by computational in parallel programing" (Expand search), "by computational _ parallel programing" (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 computational and parallel programing\") OR (\"using python python python programming\"))~".
• Removing quotes may allow a broader search: (( by computational and parallel programing ) OR ( using python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("by computational and parallel programing") OR ("using python python python programming"))*.
