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 means algorithm" » "element search algorithm" (Expand Search), "element mesh algorithm" (Expand Search)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion algorithm" (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 means algorithm"))) OR ("data using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"segment detection algorithm\") OR (\"element means algorithm\"))) OR (\"data using algorithm\"))".
• Removing quotes may allow a broader search: (((( segment detection algorithm ) OR ( element means algorithm ))) OR ( data using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("segment detection algorithm") OR ("element means algorithm"))) OR ("data using algorithm"))*.
