Perhaps you should try some spelling variations:
"image routing algorithm" » "image modeling algorithm" (Expand Search), "image finding algorithm" (Expand Search), "image making algorithm" (Expand Search), "image 1_using algorithm" (Expand Search), "image 2_using algorithm" (Expand Search), "image 3_using algorithm" (Expand Search)
"element based algorithms" » "element based algorithm" (Expand Search), "engagement based algorithms" (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)

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 algorithms") OR ("present data algorithms"))) OR ("image routing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element based algorithms\") OR (\"present data algorithms\"))) OR (\"image routing algorithm\"))".
• Removing quotes may allow a broader search: (((( element based algorithms ) OR ( present data algorithms ))) OR ( image routing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element based algorithms") OR ("present data algorithms"))) OR ("image routing algorithm"))*.
