Perhaps you should try some spelling variations:
"coder conic programming approach problem" » "coder logic programming approach problem" (Expand search), "coder cone programming approach problem" (Expand search), "coder convex programming approach problem" (Expand search), "coder conic programming approaches problems" (Expand search), "coder conic programming approaching problems" (Expand search), "coder conic programming approach produces" (Expand search), "order conic programming approach problem" (Expand search)
"_ python python python programming" » "_ pythons python python programming" (Expand search), "_ piton python python programming" (Expand search), "_ pitons 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 conic programming approach problem\") OR (\"_ python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder conic programming approach problem ) OR ( _ python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder conic programming approach problem") OR ("_ python python python programming"))*.
