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)
"fold modeling algorithm" » "fold making algorithm" (Expand Search), "field modeling algorithm" (Expand Search), "flood modeling algorithm" (Expand Search), "yield modeling algorithm" (Expand Search)
"elements rf algorithm" » "elements _ algorithm" (Expand Search), "elements ii algorithm" (Expand Search), "elements art algorithms" (Expand Search), "elements ree algorithm" (Expand Search), "elements res 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 ("fold modeling algorithm"))) OR ("elements rf algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data processing algorithm\") OR (\"fold modeling algorithm\"))) OR (\"elements rf algorithm\"))".
• Removing quotes may allow a broader search: (((( data processing algorithm ) OR ( fold modeling algorithm ))) OR ( elements rf algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data processing algorithm") OR ("fold modeling algorithm"))) OR ("elements rf algorithm"))*.
