Perhaps you should try some spelling variations:
"client sampling algorithm" » "client scheduling algorithm" (Expand Search)
"element method algorithm" » "element mould algorithm" (Expand Search), "elements method algorithm" (Expand Search)
"client finding algorithm" » "client findings 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 ("client finding algorithm"))) OR ("element method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"client sampling algorithm\") OR (\"client finding algorithm\"))) OR (\"element method algorithm\"))".
• Removing quotes may allow a broader search: (((( client sampling algorithm ) OR ( client finding algorithm ))) OR ( element method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("client sampling algorithm") OR ("client finding algorithm"))) OR ("element method algorithm"))*.
