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", "_ estimation algorithms", "_ evolution 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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"_ simulation algorithm\") OR (\"a solution algorithm\"))) OR (\"policy optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (((( _ simulation algorithm ) OR ( a solution algorithm ))) OR ( policy optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ simulation algorithm") OR ("a solution algorithm"))) OR ("policy optimisation algorithm"))*.
