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