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

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("a estimation algorithm") OR ("a solution algorithm"))) OR ("policy optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"a estimation algorithm\") OR (\"a solution algorithm\"))) OR (\"policy optimization algorithm\"))".
• Removing quotes may allow a broader search: (((( a estimation algorithm ) OR ( a solution algorithm ))) OR ( policy optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("a estimation algorithm") OR ("a solution algorithm"))) OR ("policy optimization algorithm"))*.
