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