Perhaps you should try some spelling variations:
"experiments using algorithm" » "experiments cosine algorithm" (Expand Search), "experimental using algorithm" (Expand Search)
"elements cnn algorithm" » "elements rd algorithm" (Expand Search), "elements colony algorithm" (Expand Search), "elements cosine algorithm" (Expand Search), "elements _ algorithm" (Expand Search)
"neural finding algorithm" » "neural findings 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: (((("experiments using algorithm") OR ("elements cnn algorithm"))) OR ("neural finding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"experiments using algorithm\") OR (\"elements cnn algorithm\"))) OR (\"neural finding algorithm\"))".
• Removing quotes may allow a broader search: (((( experiments using algorithm ) OR ( elements cnn algorithm ))) OR ( neural finding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("experiments using algorithm") OR ("elements cnn algorithm"))) OR ("neural finding algorithm"))*.
