Perhaps you should try some spelling variations:
"elements present algorithm" » "elements presented algorithm" (Expand Search), "elements treatment algorithm" (Expand Search), "elements forest algorithm" (Expand Search)
"plant processing algorithm" » "post processing algorithm" (Expand Search), "image processing algorithm" (Expand Search), "data processing algorithm" (Expand Search)
"element new algorithm" » "element novel algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element te algorithm" (Expand Search), "element ree 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: (((("elements present algorithm") OR ("element new algorithm"))) OR ("plant processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements present algorithm\") OR (\"element new algorithm\"))) OR (\"plant processing algorithm\"))".
• Removing quotes may allow a broader search: (((( elements present algorithm ) OR ( element new algorithm ))) OR ( plant processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements present algorithm") OR ("element new algorithm"))) OR ("plant processing algorithm"))*.
