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