Perhaps you should try some spelling variations:
"sediment sampling algorithm" » "sediment mining algorithm" (Expand Search), "sediment samples algorithm" (Expand Search), "sediment sample algorithm" (Expand Search)
"element cnn algorithm" » "element _ algorithm" (Expand Search), "element new algorithm" (Expand Search), "element em algorithm" (Expand Search)
"elements pso algorithm" » "elements two algorithms" (Expand Search), "elements _ algorithm" (Expand Search), "elements new algorithm" (Expand Search), "elements ppm algorithm" (Expand Search), "elements upon algorithm" (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: (((("element cnn algorithm") OR ("elements pso algorithm"))) OR ("sediment sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element cnn algorithm\") OR (\"elements pso algorithm\"))) OR (\"sediment sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( element cnn algorithm ) OR ( elements pso algorithm ))) OR ( sediment sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element cnn algorithm") OR ("elements pso algorithm"))) OR ("sediment sampling algorithm"))*.
