Perhaps you should try some spelling variations:
"data processing algorithm" » "data modeling algorithm" (Expand Search), "data routing algorithm" (Expand Search), "data tracking algorithm" (Expand Search), "image processing algorithm" (Expand Search)
"elements based algorithms" » "elements based algorithm" (Expand Search), "experiments based algorithms" (Expand Search), "elements related algorithms" (Expand Search)
"element erf algorithm" » "element rf algorithm" (Expand Search), "element rl algorithm" (Expand Search), "element em algorithm" (Expand Search), "element ore 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: (("data processing algorithm") OR ((("element erf algorithm") OR ("elements based algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data processing algorithm\") OR (((\"element erf algorithm\") OR (\"elements based algorithms\"))))".
• Removing quotes may allow a broader search: (( data processing algorithm ) OR ((( element erf algorithm ) OR ( elements based algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("data processing algorithm") OR ((("element erf algorithm") OR ("elements based algorithms"))))*.
