Perhaps you should try some spelling variations:
"image processing algorithm" » "image modeling algorithm" (Expand Search), "image routing algorithm" (Expand Search), "image tracking algorithm" (Expand Search)
"data processing algorithm" » "data modeling algorithm" (Expand Search), "data routing algorithm" (Expand Search), "data tracking algorithm" (Expand Search)
"element tide algorithm" » "element td3 algorithm" (Expand Search), "element leiden algorithm" (Expand Search), "element five algorithms" (Expand Search), "element te algorithm" (Expand Search), "element model algorithm" (Expand Search), "element study 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: (("element tide algorithm") OR ((("image processing algorithm") OR ("data processing algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element tide algorithm\") OR (((\"image processing algorithm\") OR (\"data processing algorithm\"))))".
• Removing quotes may allow a broader search: (( element tide algorithm ) OR ((( image processing algorithm ) OR ( data processing algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element tide algorithm") OR ((("image processing algorithm") OR ("data processing algorithm"))))*.
