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