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)
"element mesh algorithm" » "element best algorithm" (Expand Search), "element mean algorithm" (Expand Search), "element means algorithm" (Expand Search), "element method algorithm" (Expand Search)
"elements four algorithms" » "elements group algorithms" (Expand Search), "elements over algorithms" (Expand Search), "elements fe algorithms" (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: (((("element mesh algorithm") OR ("elements four algorithms"))) OR ("plant processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element mesh algorithm\") OR (\"elements four algorithms\"))) OR (\"plant processing algorithm\"))".
• Removing quotes may allow a broader search: (((( element mesh algorithm ) OR ( elements four algorithms ))) OR ( plant processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element mesh algorithm") OR ("elements four algorithms"))) OR ("plant processing algorithm"))*.
