Perhaps you should try some spelling variations:
"segment detection algorithm" » "event detection algorithm" (Expand Search), "recent detection algorithm" (Expand Search), "defect detection algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"data using algorithms" » "data pacing algorithms" (Expand Search), "data nine algorithms" (Expand Search), "data sorting algorithms" (Expand Search)

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("segment detection algorithm") OR ("element method algorithm"))) OR ("data using algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"segment detection algorithm\") OR (\"element method algorithm\"))) OR (\"data using algorithms\"))".
• Removing quotes may allow a broader search: (((( segment detection algorithm ) OR ( element method algorithm ))) OR ( data using algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("segment detection algorithm") OR ("element method algorithm"))) OR ("data using algorithms"))*.
