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)
"present data algorithms" » "present art algorithms" (Expand Search), "present all algorithms" (Expand Search), "present both algorithms" (Expand Search), "presence data algorithms" (Expand Search), "present day algorithms" (Expand Search), "recent data algorithms" (Expand Search)
"element two algorithms" » "element ml algorithms" (Expand Search), "element _ algorithms" (Expand Search), "element art algorithms" (Expand Search), "element te 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 two algorithms") OR ("present data algorithms"))) OR ("image processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element two algorithms\") OR (\"present data algorithms\"))) OR (\"image processing algorithm\"))".
• Removing quotes may allow a broader search: (((( element two algorithms ) OR ( present data algorithms ))) OR ( image processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element two algorithms") OR ("present data algorithms"))) OR ("image processing algorithm"))*.
