Perhaps you should try some spelling variations:
"client sampling algorithm" » "client mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search)
"element swarm algorithm" » "element search algorithm" (Expand Search), "element software algorithm" (Expand Search)
"element forest algorithm" » "element ore algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("client sampling algorithm") OR ("element swarm algorithm"))) OR ("element forest algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"client sampling algorithm\") OR (\"element swarm algorithm\"))) OR (\"element forest algorithm\"))".
• Removing quotes may allow a broader search: (((( client sampling algorithm ) OR ( element swarm algorithm ))) OR ( element forest algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("client sampling algorithm") OR ("element swarm algorithm"))) OR ("element forest algorithm"))*.
