Perhaps you should try some spelling variations:
"a estimation algorithms" » "a optimization algorithms", "a optimisation algorithm", "a approximation algorithms", "_ estimation algorithms", "a destination algorithms", "_ estimating algorithms"
"_ evolution algorithm" » "_ solution algorithm", "_ evolutionary algorithm", "_ convolution algorithms", "_ evaluation algorithm"
"policy estimation algorithm" » "policy optimization algorithm", "pose estimation algorithm", "motion estimation 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 algorithms") or ("_ evolution algorithm"))) or ("policy estimation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("a estimation algorithms") OR ("_ evolution algorithm"))) OR ("policy estimation algorithm"))*.
• Removing quotes may allow a broader search: (((( a estimation algorithms ) or ( _ evolution algorithm ))) or ( policy estimation algorithm ))*.
