Perhaps you should try some spelling variations:
"policy optimization algorithm" » "policy optimization algorithms", "policy optimisation algorithm", "policy estimation algorithm", "topology optimization algorithm"
"a simulation algorithm" » "a estimation algorithm", "a optimisation algorithm", "a estimation algorithms", "_ simulation algorithm"
"via solution algorithm" » "via evolution algorithm", "via convolution algorithms", "via evolutionary algorithm", "_ solution algorithm"

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