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"
"a simulation algorithm" » "a estimation algorithm", "a estimation algorithms", "a evolution algorithm", "_ simulation algorithm"
"a solution algorithm" » "a evolution algorithm", "a convolution algorithms", "a evolutionary algorithm", "_ solution algorithm", "_ solutions algorithm", "nacl solution 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 ((("a simulation algorithm") OR ("a solution algorithm"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("policy optimisation algorithm") OR ((("a simulation algorithm") OR ("a solution algorithm")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"policy optimisation algorithm\") or (((\"a simulation algorithm\") OR (\"a solution algorithm\"))))".
• Removing quotes may allow a broader search: (( policy optimisation algorithm ) or ((( a simulation algorithm ) OR ( a solution algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("policy optimisation algorithm") or ((("a simulation algorithm") OR ("a solution algorithm"))))*.
