Perhaps you should try some spelling variations:
"plant processing algorithm" » "post processing algorithm" (Expand Search), "image processing algorithm" (Expand Search), "data processing algorithm" (Expand Search)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant each algorithm" (Expand Search)
"element cnn algorithm" » "element _ algorithm" (Expand Search), "element new algorithm" (Expand Search), "element em 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 algorithm") OR ("element cnn algorithm"))) OR ("plant processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"relevant data algorithm\") OR (\"element cnn algorithm\"))) OR (\"plant processing algorithm\"))".
• Removing quotes may allow a broader search: (((( relevant data algorithm ) OR ( element cnn algorithm ))) OR ( plant processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("relevant data algorithm") OR ("element cnn algorithm"))) OR ("plant processing algorithm"))*.
