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