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)
"develop tree algorithms" » "develop three algorithms" (Expand Search), "develop art algorithms" (Expand Search), "develop two algorithms" (Expand Search), "develop new algorithms" (Expand Search), "develop targeted algorithms" (Expand Search)
"element rast algorithm" » "element best algorithm" (Expand Search), "element forest algorithm" (Expand Search), "element based algorithm" (Expand Search), "element data algorithm" (Expand Search), "element mesh algorithm" (Expand Search), "element ree 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 ((("develop tree algorithms") OR ("element rast algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data processing algorithm\") OR (((\"develop tree algorithms\") OR (\"element rast algorithm\"))))".
• Removing quotes may allow a broader search: (( data processing algorithm ) OR ((( develop tree algorithms ) OR ( element rast algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("data processing algorithm") OR ((("develop tree algorithms") OR ("element rast algorithm"))))*.
