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

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

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