Perhaps you should try some spelling variations:
"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)
"element tide algorithm" » "element td3 algorithm" (Expand Search), "element leiden algorithm" (Expand Search), "element five algorithms" (Expand Search), "element te algorithm" (Expand Search), "element model algorithm" (Expand Search), "element study 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 tide algorithm") OR ((("element method algorithm") OR ("level coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element tide algorithm\") OR (((\"element method algorithm\") OR (\"level coding algorithm\"))))".
• Removing quotes may allow a broader search: (( element tide algorithm ) OR ((( element method algorithm ) OR ( level coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element tide algorithm") OR ((("element method algorithm") OR ("level coding algorithm"))))*.
