Perhaps you should try some spelling variations:
"based sorting algorithms" » "based routing algorithm" (Expand Search), "based learning algorithms" (Expand Search), "based scoring algorithms" (Expand Search), "based testing algorithms" (Expand Search), "based dosing 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 using algorithms" » "data pacing algorithms" (Expand Search), "data nine algorithms" (Expand Search), "data finding algorithms" (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 using algorithms") OR ("based sorting algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements method algorithm\") OR (((\"data using algorithms\") OR (\"based sorting algorithms\"))))".
• Removing quotes may allow a broader search: (( elements method algorithm ) OR ((( data using algorithms ) OR ( based sorting algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("elements method algorithm") OR ((("data using algorithms") OR ("based sorting algorithms"))))*.
