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"
"_ simulation algorithms" » "_ estimation algorithms", "_ optimization algorithms", "_ estimation algorithm"
"_ solution algorithm" » "_ evolution algorithm", "_ convolution algorithms", "_ evolutionary algorithm", "_ solutions 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 optimisation algorithm") or ((("_ simulation algorithms") or ("_ solution algorithm"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("policy optimisation algorithm") OR ((("_ simulation algorithms") OR ("_ solution algorithm")))).
• Removing quotes may allow a broader search: (( policy optimisation algorithm ) or ((( _ simulation algorithms ) or ( _ solution algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("policy optimisation algorithm") or ((("_ simulation algorithms") or ("_ solution algorithm"))))*.
