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)
"fold processing algorithm" » "food processing algorithm" (Expand Search), "wood processing algorithm" (Expand Search), "post processing algorithm" (Expand Search)
"element rf algorithm" » "element _ algorithm" (Expand Search), "element em algorithm" (Expand Search), "element ii algorithm" (Expand Search), "element ree algorithm" (Expand Search), "element ore 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 ("fold processing algorithm"))) OR ("element rf algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"plant processing algorithm\") OR (\"fold processing algorithm\"))) OR (\"element rf algorithm\"))".
• Removing quotes may allow a broader search: (((( plant processing algorithm ) OR ( fold processing algorithm ))) OR ( element rf algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("plant processing algorithm") OR ("fold processing algorithm"))) OR ("element rf algorithm"))*.
