Perhaps you should try some spelling variations:
"policy optimization algorithms" » "policy optimisation algorithm", "policy estimation algorithms", "policy estimation algorithm", "topology optimization algorithms"
"_ optimized algorithm" » "_ optimized algorithms", "_ optimizer algorithms", "_ optimised algorithm"
"_ optimize algorithm" » "_ optimized algorithms", "_ optimizer algorithms", "_ optimise algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("policy optimization algorithms") or ((("_ optimize algorithm") or ("_ optimized algorithm"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("policy optimization algorithms") OR ((("_ optimize algorithm") OR ("_ optimized algorithm"))))*.
• Removing quotes may allow a broader search: (( policy optimization algorithms ) or ((( _ optimize algorithm ) or ( _ optimized algorithm ))))*.
