Perhaps you should try some spelling variations:
"element sampling algorithm" » "element mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "client sampling algorithm" (Expand Search)
"element swarm algorithm" » "element search algorithm" (Expand Search), "element software algorithm" (Expand Search)
"latent new algorithm" » "latent novel algorithm" (Expand Search), "latent _ 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: (((("latent new algorithm") OR ("element swarm algorithm"))) OR ("element sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"latent new algorithm\") OR (\"element swarm algorithm\"))) OR (\"element sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( latent new algorithm ) OR ( element swarm algorithm ))) OR ( element sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("latent new algorithm") OR ("element swarm algorithm"))) OR ("element sampling algorithm"))*.
