Perhaps you should try some spelling variations:
"client sampling algorithm" » "client scheduling algorithm" (Expand Search)
"experiments each algorithm" » "experiments approach algorithm" (Expand Search), "experiments search algorithm" (Expand Search), "experiments jaya 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)

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: (((("experiments each algorithm") OR ("element cnn algorithm"))) OR ("client sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"experiments each algorithm\") OR (\"element cnn algorithm\"))) OR (\"client sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( experiments each algorithm ) OR ( element cnn algorithm ))) OR ( client sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("experiments each algorithm") OR ("element cnn algorithm"))) OR ("client sampling algorithm"))*.
