Perhaps you should try some spelling variations:
"client sampling algorithm" » "client making algorithm" (Expand Search), "client modeling algorithm" (Expand Search), "client mining algorithm" (Expand Search)
"element mapping algorithm" » "element making algorithm" (Expand Search), "element mining algorithm" (Expand Search), "element learning algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "argument mapping algorithm" (Expand Search)
"element tide algorithm" » "element td3 algorithm" (Expand Search), "element leiden algorithm" (Expand Search), "element five algorithms" (Expand Search), "element te algorithm" (Expand Search), "element model algorithm" (Expand Search), "element study 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 tide algorithm") OR ((("element mapping algorithm") OR ("client sampling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element tide algorithm\") OR (((\"element mapping algorithm\") OR (\"client sampling algorithm\"))))".
• Removing quotes may allow a broader search: (( element tide algorithm ) OR ((( element mapping algorithm ) OR ( client sampling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element tide algorithm") OR ((("element mapping algorithm") OR ("client sampling algorithm"))))*.
