Perhaps you should try some spelling variations:
"data processing algorithm" » "data routing algorithm" (Expand Search), "data tracking algorithm" (Expand Search), "data boosting algorithm" (Expand Search), "image processing algorithm" (Expand Search)
"joint modeling algorithm" » "joint making algorithm" (Expand Search), "joint model algorithm" (Expand Search)
"element rl algorithms" » "element ml algorithms" (Expand Search), "element rl algorithm" (Expand Search), "element art algorithms" (Expand Search), "element ore algorithms" (Expand Search), "element ree algorithms" (Expand Search), "element _ 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 ("joint modeling algorithm"))) OR ("element rl algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data processing algorithm\") OR (\"joint modeling algorithm\"))) OR (\"element rl algorithms\"))".
• Removing quotes may allow a broader search: (((( data processing algorithm ) OR ( joint modeling algorithm ))) OR ( element rl algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("data processing algorithm") OR ("joint modeling algorithm"))) OR ("element rl algorithms"))*.
