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