Perhaps you should try some spelling variations:
"plant processing algorithm" » "plant processing algorithms" (Expand Search), "image processing algorithm" (Expand Search), "text processing algorithm" (Expand Search), "melt processing algorithm" (Expand Search)
"element other algorithms" » "element deer algorithm" (Expand Search), "elements other algorithms" (Expand Search)
"element mesh algorithm" » "element deer algorithm" (Expand Search), "element search algorithm" (Expand Search), "elements 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: (("plant processing algorithm") OR ((("element mesh algorithm") OR ("element other algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"plant processing algorithm\") OR (((\"element mesh algorithm\") OR (\"element other algorithms\"))))".
• Removing quotes may allow a broader search: (( plant processing algorithm ) OR ((( element mesh algorithm ) OR ( element other algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("plant processing algorithm") OR ((("element mesh algorithm") OR ("element other algorithms"))))*.
