Perhaps you should try some spelling variations:
"element sampling algorithm" » "element scheduling algorithm" (Expand Search), "elements sampling algorithm" (Expand Search)
"elemental two algorithms" » "elemental _ algorithms" (Expand Search), "elementary two algorithms" (Expand Search), "elements two algorithms" (Expand Search), "elementsal two algorithms" (Expand Search)
"elemental xrd algorithm" » "elemental rd algorithm" (Expand Search), "elementary xrd algorithm" (Expand Search), "elements xrd algorithm" (Expand Search), "elementsal xrd 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: (((("elemental xrd algorithm") OR ("elemental two algorithms"))) OR ("element sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elemental xrd algorithm\") OR (\"elemental two algorithms\"))) OR (\"element sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( elemental xrd algorithm ) OR ( elemental two algorithms ))) OR ( element sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elemental xrd algorithm") OR ("elemental two algorithms"))) OR ("element sampling algorithm"))*.
