Perhaps you should try some spelling variations:
"_ simulation algorithms" » "_ estimation algorithms", "_ optimization algorithms"
"a solution algorithm" » "a evolution algorithm", "a convolution algorithms", "a evolutionary algorithm", "_ solution algorithm", "_ solutions algorithm", "nacl solution algorithm"
"policy estimation algorithm" » "policy optimization algorithm", "pose estimation algorithm", "motion estimation algorithm"

Try widening your search to All Fields.

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

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