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)
"element tested algorithms" » "element based algorithms" (Expand Search), "element best algorithms" (Expand Search), "element based algorithm" (Expand Search), "elements tended 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: (((("element tested algorithms") OR ("element erf algorithm"))) OR ("data processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element tested algorithms\") OR (\"element erf algorithm\"))) OR (\"data processing algorithm\"))".
• Removing quotes may allow a broader search: (((( element tested algorithms ) OR ( element erf algorithm ))) OR ( data processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element tested algorithms") OR ("element erf algorithm"))) OR ("data processing algorithm"))*.
