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