Perhaps you should try some spelling variations:
"implement fusion algorithm" » "implement lasso algorithm" (Expand Search), "implemented fusion algorithm" (Expand Search), "implementing fusion algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"element two algorithms" » "element ml algorithms" (Expand Search), "element _ algorithms" (Expand Search), "element art algorithms" (Expand Search), "element te algorithms" (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: (((("implement fusion algorithm") OR ("element two algorithms"))) OR ("neural coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"implement fusion algorithm\") OR (\"element two algorithms\"))) OR (\"neural coding algorithm\"))".
• Removing quotes may allow a broader search: (((( implement fusion algorithm ) OR ( element two algorithms ))) OR ( neural coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("implement fusion algorithm") OR ("element two algorithms"))) OR ("neural coding algorithm"))*.
