Perhaps you should try some spelling variations:
"client sampling algorithm" » "client mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search)
"elements upon algorithm" » "elements ppo algorithm" (Expand Search), "elements fusion algorithm" (Expand Search), "elements pso algorithm" (Expand Search), "elements ppm algorithm" (Expand Search)
"elemental iron algorithm" » "elemental pso algorithm" (Expand Search), "elemental ii algorithm" (Expand Search), "elemental cnn 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: (((("elements upon algorithm") OR ("elemental iron algorithm"))) OR ("client sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements upon algorithm\") OR (\"elemental iron algorithm\"))) OR (\"client sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( elements upon algorithm ) OR ( elemental iron algorithm ))) OR ( client sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements upon algorithm") OR ("elemental iron algorithm"))) OR ("client sampling algorithm"))*.
