Perhaps you should try some spelling variations:
"_ computational coder detection problem" » "_ computational code detection problem" (Expand search), "_ computational codes detection problem" (Expand search), "_ computational model detection problem" (Expand search), "_ computational coder selection problem" (Expand search), "_ computational coder detection program" (Expand search), "_ computational coder demarcation problem" (Expand search), "_ computational border detection problem" (Expand search), "_ computational corner detection problem" (Expand search)
"sensor based python python programming" » "sensor based pythons python programming" (Expand search), "sensor based piton python programming" (Expand search), "sensor based pitons python programming" (Expand search), "sensor based path python programming" (Expand search), "sensor and python python programming" (Expand search), "sensor gate 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: "((\"_ computational coder detection problem\") OR (\"sensor based python python programming\"))~".
• Removing quotes may allow a broader search: (( _ computational coder detection problem ) OR ( sensor based python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("_ computational coder detection problem") OR ("sensor based python python programming"))*.
