Perhaps you should try some spelling variations:
"element controls algorithm" » "element control algorithm" (Expand Search), "element control algorithms" (Expand Search), "element centrality algorithm" (Expand Search), "element contents algorithm" (Expand Search), "element content algorithm" (Expand Search), "select controls algorithm" (Expand Search)
"element sampling algorithm" » "element mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "client sampling algorithm" (Expand Search)
"element te algorithm" » "element tide algorithm" (Expand Search), "element new algorithm" (Expand Search), "element de algorithms" (Expand Search), "element _ algorithm" (Expand Search), "element data algorithm" (Expand Search), "element mesh 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 te algorithm") OR ("element controls algorithm"))) OR ("element sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element te algorithm\") OR (\"element controls algorithm\"))) OR (\"element sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( element te algorithm ) OR ( element controls algorithm ))) OR ( element sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element te algorithm") OR ("element controls algorithm"))) OR ("element sampling algorithm"))*.
