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" » "image modeling algorithm" (Expand Search), "image routing algorithm" (Expand Search), "image tracking algorithm" (Expand Search)
"element te algorithms" » "element de algorithms" (Expand Search), "element tree algorithms" (Expand Search), "element two algorithms" (Expand Search), "element _ algorithms" (Expand Search), "element g algorithms" (Expand Search), "element data 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: (("element te algorithms") OR ((("data processing algorithm") OR ("image processing algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element te algorithms\") OR (((\"data processing algorithm\") OR (\"image processing algorithm\"))))".
• Removing quotes may allow a broader search: (( element te algorithms ) OR ((( data processing algorithm ) OR ( image processing algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element te algorithms") OR ((("data processing algorithm") OR ("image processing algorithm"))))*.
