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