Perhaps you should try some spelling variations:
"modified parameter estimation algorithm" » "modified parameter estimates algorithm", "modified parameter optimization algorithm"
"modified near approximation algorithms" » "modified one approximation algorithms", "modified network approximation algorithms", "modified _ approximation algorithms", "modified seird approximation algorithms", "modified adam approximation algorithms"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameter estimation algorithm") OR ("modified near approximation algorithms"))~.
• Removing quotes may allow a broader search: (( modified parameter estimation algorithm ) or ( modified near approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified parameter estimation algorithm") or ("modified near approximation algorithms"))*.
