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)
"element learning algorithms" » "excellent learning algorithms" (Expand Search), "student learning algorithms" (Expand Search), "agent learning algorithms" (Expand Search)
"element em algorithm" » "element new algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element ii algorithm" (Expand Search), "element ree algorithm" (Expand Search), "element g 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 ((("element em algorithm") OR ("element learning algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"image processing algorithm\") OR (((\"element em algorithm\") OR (\"element learning algorithms\"))))".
• Removing quotes may allow a broader search: (( image processing algorithm ) OR ((( element em algorithm ) OR ( element learning algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("image processing algorithm") OR ((("element em algorithm") OR ("element learning algorithms"))))*.
