Perhaps you should try some spelling variations:
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"data using algorithms" » "data pacing algorithms" (Expand Search), "data nine algorithms" (Expand Search), "data sorting algorithms" (Expand Search)
"element pass algorithm" » "element lasso algorithm" (Expand Search), "element pso algorithm" (Expand Search), "element rast algorithm" (Expand Search), "element data algorithm" (Expand Search), "element mesh 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: (((("element pass algorithm") OR ("element method algorithm"))) OR ("data using algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element pass algorithm\") OR (\"element method algorithm\"))) OR (\"data using algorithms\"))".
• Removing quotes may allow a broader search: (((( element pass algorithm ) OR ( element method algorithm ))) OR ( data using algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("element pass algorithm") OR ("element method algorithm"))) OR ("data using algorithms"))*.
