Perhaps you should try some spelling variations:
"fold processing algorithm" » "food processing algorithm" (Expand Search), "wood processing algorithm" (Expand Search), "post processing algorithm" (Expand Search)
"element forest algorithm" » "element ore 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: (("fold processing algorithm") OR ((("element forest algorithm") OR ("element new algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"fold processing algorithm\") OR (((\"element forest algorithm\") OR (\"element new algorithm\"))))".
• Removing quotes may allow a broader search: (( fold processing algorithm ) OR ((( element forest algorithm ) OR ( element new algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("fold processing algorithm") OR ((("element forest algorithm") OR ("element new algorithm"))))*.
