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