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