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