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