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 trpo algorithm" » "present ppo algorithm" (Expand Search), "present carlo algorithm" (Expand Search), "present sippo algorithm" (Expand Search), "present cryo algorithm" (Expand Search), "present proof algorithm" (Expand Search), "present tab algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"present trpo algorithm\") OR (((\"implement routing algorithm\") OR (\"neural coding algorithm\"))))~".
• Removing quotes may allow a broader search: (( present trpo algorithm ) OR ((( implement routing algorithm ) OR ( neural coding algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("present trpo algorithm") OR ((("implement routing algorithm") OR ("neural coding algorithm"))))*.
