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 method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"element novel algorithm" » "element forest algorithm" (Expand Search), "element model algorithm" (Expand Search), "element ore algorithm" (Expand Search), "elements over 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 novel algorithm") OR ("element method algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"image processing algorithm\") OR (((\"element novel algorithm\") OR (\"element method algorithm\"))))".
• Removing quotes may allow a broader search: (( image processing algorithm ) OR ((( element novel algorithm ) OR ( element method algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("image processing algorithm") OR ((("element novel algorithm") OR ("element method algorithm"))))*.
