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