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 codings algorithm" » "data cosine algorithm" (Expand Search), "data modeling algorithm" (Expand Search), "data hastings algorithm" (Expand Search), "data recordings algorithm" (Expand Search), "data encoding algorithm" (Expand Search), "data codes algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search), "elements method 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 method algorithm") OR ((("data codings algorithm") OR ("image processing algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element method algorithm\") OR (((\"data codings algorithm\") OR (\"image processing algorithm\"))))".
• Removing quotes may allow a broader search: (( element method algorithm ) OR ((( data codings algorithm ) OR ( image processing algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element method algorithm") OR ((("data codings algorithm") OR ("image processing algorithm"))))*.
