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