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)
"time using algorithm" » "time using algorithms" (Expand Search), "time routing algorithm" (Expand Search), "time fusion algorithm" (Expand Search)
"relevant data algorithms" » "relevant art algorithms" (Expand Search), "relevant all algorithms" (Expand Search), "relevant both 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 ("time using algorithm"))) OR ("relevant data algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data processing algorithm\") OR (\"time using algorithm\"))) OR (\"relevant data algorithms\"))".
• Removing quotes may allow a broader search: (((( data processing algorithm ) OR ( time using algorithm ))) OR ( relevant data algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("data processing algorithm") OR ("time using algorithm"))) OR ("relevant data algorithms"))*.
