Perhaps you should try some spelling variations:
"stool processing algorithm" » "stool modeling algorithm" (Expand Search), "stool routing algorithm" (Expand Search), "stool tracking algorithm" (Expand Search), "wood processing algorithm" (Expand Search), "food processing algorithm" (Expand Search), "signal processing algorithm" (Expand Search)
"element ddpg algorithm" » "element ppo algorithm" (Expand Search), "element dbo algorithm" (Expand Search), "element hip algorithm" (Expand Search), "element g algorithm" (Expand Search), "element data algorithm" (Expand Search)
"element based algorithm" » "engagement based 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: (("stool processing algorithm") OR ((("element based algorithm") OR ("element ddpg algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"stool processing algorithm\") OR (((\"element based algorithm\") OR (\"element ddpg algorithm\"))))".
• Removing quotes may allow a broader search: (( stool processing algorithm ) OR ((( element based algorithm ) OR ( element ddpg algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("stool processing algorithm") OR ((("element based algorithm") OR ("element ddpg algorithm"))))*.
