Perhaps you should try some spelling variations:
"sediment sampling algorithm" » "sediment mining algorithm" (Expand Search), "sediment samples algorithm" (Expand Search), "sediment sample 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)
"element ore algorithm" » "element rf algorithm" (Expand Search), "element rl algorithm" (Expand Search), "element erf algorithm" (Expand Search), "element te algorithm" (Expand Search), "element ree algorithm" (Expand Search), "element model 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 ore algorithm") OR ("element mesh algorithm"))) OR ("sediment sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element ore algorithm\") OR (\"element mesh algorithm\"))) OR (\"sediment sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( element ore algorithm ) OR ( element mesh algorithm ))) OR ( sediment sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element ore algorithm") OR ("element mesh algorithm"))) OR ("sediment sampling algorithm"))*.
