Perhaps you should try some spelling variations:
"via simulation algorithm" » "via solution algorithm", "via optimisation algorithm", "via estimation algorithms", "_ simulation algorithm", "3d simulation algorithm", "mri simulation algorithm", "vi_ simulation algorithm"
"a simulation algorithm" » "a solution algorithm", "a optimisation algorithm", "a estimation algorithms", "_ simulation 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 ((("via simulation algorithm") OR ("a simulation algorithm"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("policy estimation algorithm") OR ((("via simulation algorithm") OR ("a simulation algorithm")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"policy estimation algorithm\") or (((\"via simulation algorithm\") OR (\"a simulation algorithm\"))))".
• Removing quotes may allow a broader search: (( policy estimation algorithm ) or ((( via simulation algorithm ) OR ( a simulation algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("policy estimation algorithm") or ((("via simulation algorithm") OR ("a simulation algorithm"))))*.
