Perhaps you should try some spelling variations:
"select detection algorithm" » "defect detection algorithm" (Expand Search), "selective detection algorithm" (Expand Search), "segment detection algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean 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: (((("select detection algorithm") OR ("element method algorithm"))) OR ("data using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"select detection algorithm\") OR (\"element method algorithm\"))) OR (\"data using algorithm\"))".
• Removing quotes may allow a broader search: (((( select detection algorithm ) OR ( element method algorithm ))) OR ( data using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("select detection algorithm") OR ("element method algorithm"))) OR ("data using algorithm"))*.
