Perhaps you should try some spelling variations:
"implement routing algorithm" » "implement routine algorithm" (Expand Search), "implement modeling algorithm" (Expand Search), "implement finding algorithm" (Expand Search), "implement making algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"present cc3d algorithm" » "present cscap algorithm" (Expand Search), "present cnn algorithm" (Expand Search), "present wold algorithm" (Expand Search), "present cryo 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: (("present cc3d algorithm") OR ((("implement routing algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"present cc3d algorithm\") OR (((\"implement routing algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( present cc3d algorithm ) OR ((( implement routing algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("present cc3d algorithm") OR ((("implement routing algorithm") OR ("neural coding algorithm"))))*.
