Perhaps you should try some spelling variations:
"stool modeling algorithm" » "stool making algorithm" (Expand Search), "flood modeling algorithm" (Expand Search), "spatial modeling 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 modeling algorithm") OR ((("element based algorithm") OR ("element ddpg algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"stool modeling algorithm\") OR (((\"element based algorithm\") OR (\"element ddpg algorithm\"))))".
• Removing quotes may allow a broader search: (( stool modeling algorithm ) OR ((( element based algorithm ) OR ( element ddpg algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("stool modeling algorithm") OR ((("element based algorithm") OR ("element ddpg algorithm"))))*.
