Perhaps you should try some spelling variations:
"policy estimation algorithms" » "policy optimization algorithms", "policy optimisation algorithm", "policy approximation algorithms", "pose estimation algorithms", "motion estimation algorithms"
"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.

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