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

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