Perhaps you should try some spelling variations:
"element learner algorithm" » "element learning algorithm" (Expand Search), "element learning algorithms" (Expand Search), "element search algorithm" (Expand Search)
"plant processing algorithm" » "post processing algorithm" (Expand Search), "image processing algorithm" (Expand Search), "data processing algorithm" (Expand Search)
"element ore algorithm" » "element rf algorithm" (Expand Search), "element rl algorithm" (Expand Search), "element erf algorithm" (Expand Search), "element te algorithm" (Expand Search), "element ree algorithm" (Expand Search), "element model 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: (("plant processing algorithm") OR ((("element ore algorithm") OR ("element learner algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"plant processing algorithm\") OR (((\"element ore algorithm\") OR (\"element learner algorithm\"))))".
• Removing quotes may allow a broader search: (( plant processing algorithm ) OR ((( element ore algorithm ) OR ( element learner algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("plant processing algorithm") OR ((("element ore algorithm") OR ("element learner algorithm"))))*.
