Perhaps you should try some spelling variations:
"data sorting algorithms" » "data routing algorithm" (Expand Search), "data learning algorithms" (Expand Search), "data working algorithms" (Expand Search), "data supporting algorithms" (Expand Search), "data settings algorithms" (Expand Search)
"image routing algorithms" » "image routing algorithm" (Expand Search), "image using algorithms" (Expand Search), "image training algorithms" (Expand Search), "image 1_using algorithms" (Expand Search), "image 2_using algorithms" (Expand Search), "image 3_using algorithms" (Expand Search)
"elements method algorithm" » "elements network algorithm" (Expand Search), "elements means algorithm" (Expand Search), "elements mean algorithm" (Expand Search), "element method 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: (("elements method algorithm") OR ((("data sorting algorithms") OR ("image routing algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements method algorithm\") OR (((\"data sorting algorithms\") OR (\"image routing algorithms\"))))".
• Removing quotes may allow a broader search: (( elements method algorithm ) OR ((( data sorting algorithms ) OR ( image routing algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("elements method algorithm") OR ((("data sorting algorithms") OR ("image routing algorithms"))))*.
