Perhaps you should try some spelling variations:
"element method algorithm" » "element mould algorithm" (Expand Search), "elements method algorithm" (Expand Search)
"present data algorithms" » "present jaya algorithm" (Expand Search)
"element matching algorithm" » "elements matching algorithm" (Expand Search), "element machine 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 method algorithm") OR ("present data algorithms"))) OR ("element matching algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element method algorithm\") OR (\"present data algorithms\"))) OR (\"element matching algorithm\"))".
• Removing quotes may allow a broader search: (((( element method algorithm ) OR ( present data algorithms ))) OR ( element matching algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element method algorithm") OR ("present data algorithms"))) OR ("element matching algorithm"))*.
