Perhaps you should try some spelling variations:
"image processing algorithm" » "image routing algorithm" (Expand Search), "image tracking algorithm" (Expand Search), "image boosting algorithm" (Expand Search)
"data modeling algorithm" » "data making algorithm" (Expand Search), "data modelling algorithm" (Expand Search), "data models algorithm" (Expand Search)
"element de algorithms" » "element mdem algorithms" (Expand Search), "element ml algorithms" (Expand Search), "element _ algorithms" (Expand Search), "element te algorithms" (Expand Search), "elements fe algorithms" (Expand Search), "element fbe 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 de algorithms") OR ((("data modeling algorithm") OR ("image processing algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element de algorithms\") OR (((\"data modeling algorithm\") OR (\"image processing algorithm\"))))".
• Removing quotes may allow a broader search: (( element de algorithms ) OR ((( data modeling algorithm ) OR ( image processing algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element de algorithms") OR ((("data modeling algorithm") OR ("image processing algorithm"))))*.
