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 ml algorithms" » "elemental _ algorithms" (Expand Search), "elemental rd algorithm" (Expand Search), "elementary ml algorithms" (Expand Search), "elements ml algorithms" (Expand Search), "elementsal ml algorithms" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("elemental two algorithms") OR ("elemental ml algorithms"))) OR ("element sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elemental two algorithms\") OR (\"elemental ml algorithms\"))) OR (\"element sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( elemental two algorithms ) OR ( elemental ml algorithms ))) OR ( element sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elemental two algorithms") OR ("elemental ml algorithms"))) OR ("element sampling algorithm"))*.
