Perhaps you should try some spelling variations:
"client sampling algorithm" » "client mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search)
"elements under algorithm" » "elements new algorithm" (Expand Search), "elements tide algorithm" (Expand Search), "elements other algorithms" (Expand Search), "elements tended algorithm" (Expand Search)
"element mesh algorithm" » "element best algorithm" (Expand Search), "element mean algorithm" (Expand Search), "element means algorithm" (Expand Search), "element method 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 mesh algorithm") OR ("elements under algorithm"))) OR ("client sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element mesh algorithm\") OR (\"elements under algorithm\"))) OR (\"client sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( element mesh algorithm ) OR ( elements under algorithm ))) OR ( client sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element mesh algorithm") OR ("elements under algorithm"))) OR ("client sampling algorithm"))*.
