Perhaps you should try some spelling variations:
"elements tended algorithms" » "elements tested algorithms" (Expand Search), "elements based algorithms" (Expand Search), "elements three algorithms" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"level coding algorithm" » "level cosine algorithm" (Expand Search), "level modeling algorithm" (Expand Search), "level finding algorithm" (Expand Search), "level according algorithm" (Expand Search), "level using 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: (("elements tended algorithms") OR ((("element method algorithm") OR ("level coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements tended algorithms\") OR (((\"element method algorithm\") OR (\"level coding algorithm\"))))".
• Removing quotes may allow a broader search: (( elements tended algorithms ) OR ((( element method algorithm ) OR ( level coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements tended algorithms") OR ((("element method algorithm") OR ("level coding algorithm"))))*.
