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 pass algorithm" » "element lasso algorithm" (Expand Search), "element pso algorithm" (Expand Search), "element rast algorithm" (Expand Search), "element data algorithm" (Expand Search), "element mesh algorithm" (Expand Search)
"elements mges algorithm" » "elements means algorithm" (Expand Search), "elements mogwo algorithm" (Expand Search), "elements magic 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 ((("element pass algorithm") OR ("elements mges algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data processing algorithm\") OR (((\"element pass algorithm\") OR (\"elements mges algorithm\"))))".
• Removing quotes may allow a broader search: (( data processing algorithm ) OR ((( element pass algorithm ) OR ( elements mges algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("data processing algorithm") OR ((("element pass algorithm") OR ("elements mges algorithm"))))*.
