Perhaps you should try some spelling variations:
"by computational coder control problems" » "by computational code control problems" (Expand search), "by computational codes control problems" (Expand search), "by computational model control problems" (Expand search), "_ computational coder control problems" (Expand search), "and computational coder control problems" (Expand search), "by computational coder control program" (Expand search), "by computational poder control problems" (Expand search), "by computational encoder control problems" (Expand search), "by computational poder controle problems" (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 coder control problems\") OR (\"using python python python programming\"))~".
• Removing quotes may allow a broader search: (( by computational coder control problems ) OR ( using python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("by computational coder control problems") OR ("using python python python programming"))*.
