Perhaps you should try some spelling variations:
"image 3_routing algorithm" » "image routing algorithm" (Expand Search), "image boosting algorithm" (Expand Search), "image 3_resting algorithm" (Expand Search), "image 3_using algorithm" (Expand Search), "image 3_targeting algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"derived using algorithm" » "derived using algorithms" (Expand Search), "derived routing algorithm" (Expand Search), "derived fusion 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 3_routing algorithm") OR ("derived using algorithm"))) OR ("element method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"image 3_routing algorithm\") OR (\"derived using algorithm\"))) OR (\"element method algorithm\"))".
• Removing quotes may allow a broader search: (((( image 3_routing algorithm ) OR ( derived using algorithm ))) OR ( element method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("image 3_routing algorithm") OR ("derived using algorithm"))) OR ("element method algorithm"))*.
