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 network algorithm" » "element new algorithm" (Expand Search), "alignment network algorithm" (Expand Search)
"elements ppo algorithm" » "elements pso algorithm" (Expand Search), "elements two algorithms" (Expand Search), "elements _ algorithm" (Expand Search), "elements ppm algorithm" (Expand Search), "elements upon 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 ((("elements ppo algorithm") OR ("element network algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data processing algorithm\") OR (((\"elements ppo algorithm\") OR (\"element network algorithm\"))))".
• Removing quotes may allow a broader search: (( data processing algorithm ) OR ((( elements ppo algorithm ) OR ( element network algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("data processing algorithm") OR ((("elements ppo algorithm") OR ("element network algorithm"))))*.
