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 based algorithm" » "engagement based algorithm" (Expand Search)
"element rl algorithms" » "element ml algorithms" (Expand Search), "element rl algorithm" (Expand Search), "element art algorithms" (Expand Search), "element ore algorithms" (Expand Search), "element ree algorithms" (Expand Search), "element _ 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 based algorithm") OR ("element rl algorithms"))) OR ("image processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element based algorithm\") OR (\"element rl algorithms\"))) OR (\"image processing algorithm\"))".
• Removing quotes may allow a broader search: (((( element based algorithm ) OR ( element rl algorithms ))) OR ( image processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element based algorithm") OR ("element rl algorithms"))) OR ("image processing algorithm"))*.
