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