Perhaps you should try some spelling variations:
"complement novel algorithm" » "completely novel algorithm" (Expand Search), "complement low algorithm" (Expand Search), "complement forest algorithm" (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: (((("complement novel algorithm") OR ("element method algorithm"))) OR ("level coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"complement novel algorithm\") OR (\"element method algorithm\"))) OR (\"level coding algorithm\"))".
• Removing quotes may allow a broader search: (((( complement novel algorithm ) OR ( element method algorithm ))) OR ( level coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("complement novel algorithm") OR ("element method algorithm"))) OR ("level coding algorithm"))*.
