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 rf algorithm" » "element _ algorithm" (Expand Search), "element ii algorithm" (Expand Search), "element art algorithms" (Expand Search), "element ore algorithm" (Expand Search), "element ree algorithm" (Expand Search)
"elements b algorithms" » "elements _ algorithms" (Expand Search), "elements b algorithm" (Expand Search), "elements 5 algorithms" (Expand Search), "element _ algorithms" (Expand Search), "element g algorithms" (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 rf algorithm") OR ("elements b algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data processing algorithm\") OR (((\"element rf algorithm\") OR (\"elements b algorithms\"))))".
• Removing quotes may allow a broader search: (( data processing algorithm ) OR ((( element rf algorithm ) OR ( elements b algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("data processing algorithm") OR ((("element rf algorithm") OR ("elements b algorithms"))))*.
