Perhaps you should try some spelling variations:
"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)
"relevant data algorithms" » "relevant art algorithms" (Expand Search), "relevant all algorithms" (Expand Search), "relevant both algorithms" (Expand Search)
"complement c3 algorithm" » "complement _ algorithm" (Expand Search), "complement 5a algorithm" (Expand Search), "complement low algorithm" (Expand Search), "complement cc3d algorithm" (Expand Search), "complement cnn algorithm" (Expand Search), "complement td3 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: (((("relevant data algorithms") OR ("complement c3 algorithm"))) OR ("level coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"relevant data algorithms\") OR (\"complement c3 algorithm\"))) OR (\"level coding algorithm\"))".
• Removing quotes may allow a broader search: (((( relevant data algorithms ) OR ( complement c3 algorithm ))) OR ( level coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("relevant data algorithms") OR ("complement c3 algorithm"))) OR ("level coding algorithm"))*.
