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)
"presence data algorithm" » "presence data algorithms" (Expand Search), "presence update algorithm" (Expand Search), "presence atlas algorithm" (Expand Search), "prevalence data algorithm" (Expand Search)
"element ore algorithm" » "element rf algorithm" (Expand Search), "element rl algorithm" (Expand Search), "element erf algorithm" (Expand Search), "element te algorithm" (Expand Search), "element fbe 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: (((("element ore algorithm") OR ("presence data algorithm"))) OR ("data processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element ore algorithm\") OR (\"presence data algorithm\"))) OR (\"data processing algorithm\"))".
• Removing quotes may allow a broader search: (((( element ore algorithm ) OR ( presence data algorithm ))) OR ( data processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element ore algorithm") OR ("presence data algorithm"))) OR ("data processing algorithm"))*.
