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)
"defined using algorithm" » "defined using algorithms" (Expand Search), "defined routing algorithm" (Expand Search), "defined fusion algorithm" (Expand Search), "derived using algorithm" (Expand Search), "trained using algorithm" (Expand Search), "determined using algorithm" (Expand Search)
"data finding algorithm" » "path finding algorithm" (Expand Search), "data fitting algorithm" (Expand Search), "case finding 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: (((("data finding algorithm") OR ("defined using algorithm"))) OR ("element method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data finding algorithm\") OR (\"defined using algorithm\"))) OR (\"element method algorithm\"))".
• Removing quotes may allow a broader search: (((( data finding algorithm ) OR ( defined using algorithm ))) OR ( element method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data finding algorithm") OR ("defined using algorithm"))) OR ("element method algorithm"))*.
