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)
"based models algorithm" » "based mould algorithm" (Expand Search), "based deer algorithm" (Expand Search), "based modeling 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 method algorithm") OR ((("client sampling algorithm") OR ("based models algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element method algorithm\") OR (((\"client sampling algorithm\") OR (\"based models algorithm\"))))".
• Removing quotes may allow a broader search: (( element method algorithm ) OR ((( client sampling algorithm ) OR ( based models algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element method algorithm") OR ((("client sampling algorithm") OR ("based models algorithm"))))*.
