Perhaps you should try some spelling variations:
"image 1_routing algorithm" » "image routing algorithm" (Expand Search), "image boosting algorithm" (Expand Search), "image 1_resting algorithm" (Expand Search), "image 1_reducing algorithm" (Expand Search), "image 1_using algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"solved using algorithm" » "solved using algorithms" (Expand Search), "solved routing algorithm" (Expand Search), "solved 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 1_routing algorithm") OR ("solved using algorithm"))) OR ("element method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"image 1_routing algorithm\") OR (\"solved using algorithm\"))) OR (\"element method algorithm\"))".
• Removing quotes may allow a broader search: (((( image 1_routing algorithm ) OR ( solved using algorithm ))) OR ( element method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("image 1_routing algorithm") OR ("solved using algorithm"))) OR ("element method algorithm"))*.
