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), "elements method algorithm" (Expand Search)
"data finding algorithm" » "path finding algorithm" (Expand Search), "data fitting algorithm" (Expand Search), "case finding 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: (((("element method algorithm") OR ("segment detection algorithm"))) OR ("data finding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element method algorithm\") OR (\"segment detection algorithm\"))) OR (\"data finding algorithm\"))".
• Removing quotes may allow a broader search: (((( element method algorithm ) OR ( segment detection algorithm ))) OR ( data finding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element method algorithm") OR ("segment detection algorithm"))) OR ("data finding algorithm"))*.
