Perhaps you should try some spelling variations:
"image sharing algorithm" » "image learning algorithms" (Expand Search), "image search algorithm" (Expand Search), "image swarm algorithm" (Expand Search)
"elements method algorithm" » "elements mould algorithm" (Expand Search)
"defined using algorithm" » "defined cosine algorithm" (Expand Search), "designed using 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 sharing algorithm") OR ("defined using algorithm"))) OR ("elements method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"image sharing algorithm\") OR (\"defined using algorithm\"))) OR (\"elements method algorithm\"))".
• Removing quotes may allow a broader search: (((( image sharing algorithm ) OR ( defined using algorithm ))) OR ( elements method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("image sharing algorithm") OR ("defined using algorithm"))) OR ("elements method algorithm"))*.
