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)
"present data algorithm" » "present data algorithms" (Expand Search), "present update algorithm" (Expand Search), "present each algorithm" (Expand Search), "patient data algorithm" (Expand Search)
"element erf algorithm" » "element rf algorithm" (Expand Search), "element em algorithm" (Expand Search), "element rl algorithm" (Expand Search), "element ore algorithm" (Expand Search), "element mesh 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: (((("present data algorithm") OR ("element erf algorithm"))) OR ("plant processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"present data algorithm\") OR (\"element erf algorithm\"))) OR (\"plant processing algorithm\"))".
• Removing quotes may allow a broader search: (((( present data algorithm ) OR ( element erf algorithm ))) OR ( plant processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("present data algorithm") OR ("element erf algorithm"))) OR ("plant processing algorithm"))*.
