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