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