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