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)
"data using algorithms" » "data pacing algorithms" (Expand Search), "data nine algorithms" (Expand Search), "data finding algorithms" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean 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 sorting algorithms") OR ("data using algorithms"))) OR ("element method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"image sorting algorithms\") OR (\"data using algorithms\"))) OR (\"element method algorithm\"))".
• Removing quotes may allow a broader search: (((( image sorting algorithms ) OR ( data using algorithms ))) OR ( element method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("image sorting algorithms") OR ("data using algorithms"))) OR ("element method algorithm"))*.
