Perhaps you should try some spelling variations:
"coder sampling detection algorithm based" » "coder sampling detection algorithms based" (Expand search), "coder sampling selection algorithm based" (Expand search), "coder tampering detection algorithm based" (Expand search), "coder sampling reduction algorithm based" (Expand search), "under sampling detection algorithm based" (Expand search), "over sampling detection algorithm based" (Expand search), "core sampling detection algorithm based" (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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("coder sampling detection algorithm based") OR ("_ python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder sampling detection algorithm based\") OR (\"_ python python python programming\"))".
• Removing quotes may allow a broader search: (( coder sampling detection algorithm based ) OR ( _ python python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("coder sampling detection algorithm based") OR ("_ python python python programming"))*.
