Perhaps you should try some spelling variations:
"coder segmentation of linear programming" » "color segmentation of linear programming" (Expand search), "over segmentation of linear programming" (Expand search), "gender segmentation of linear programming" (Expand search)
"detection in python python programming" » "detection in pythons python programming" (Expand search), "detection in piton python programming" (Expand search), "detection in pitons python programming" (Expand search), "detection and python python programming" (Expand search), "detection _ 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: "((\"coder segmentation of linear programming\") OR (\"detection in python python programming\"))~".
• Removing quotes may allow a broader search: (( coder segmentation of linear programming ) OR ( detection in python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder segmentation of linear programming") OR ("detection in python python programming"))*.
