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