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