Perhaps you should try some spelling variations:
"based computational can controller problem" » "and computational can controller problem" (Expand search), "by computational can controller problem" (Expand search), "based computational can control problem" (Expand search), "based computational can controller role" (Expand search), "based computational can controlled probe" (Expand search), "based computational and controller problem" (Expand search), "based computacional canny controller problem" (Expand search), "based computational cost controller problem" (Expand search), "based computational _ controller 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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computational can controller problem\") OR (\"using python python python programming\"))~".
• Removing quotes may allow a broader search: (( based computational can controller problem ) OR ( using python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computational can controller problem") OR ("using python python python programming"))*.
