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