Perhaps you should try some spelling variations:
"image sorting algorithms" » "image routing algorithm" (Expand Search), "image learning algorithms" (Expand Search), "lineage sorting algorithms" (Expand Search), "image showing algorithms" (Expand Search)
"element network algorithm" » "element new algorithm" (Expand Search), "alignment network algorithm" (Expand Search)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data 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: (((("data using algorithm") OR ("image sorting algorithms"))) OR ("element network algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data using algorithm\") OR (\"image sorting algorithms\"))) OR (\"element network algorithm\"))".
• Removing quotes may allow a broader search: (((( data using algorithm ) OR ( image sorting algorithms ))) OR ( element network algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data using algorithm") OR ("image sorting algorithms"))) OR ("element network algorithm"))*.
