Perhaps you should try some spelling variations:
"modified parameters optimization algorithms" » "modified parameter optimization algorithms", "modified parameter estimation algorithms", "modified parameters optimisation algorithm", "modified parameters estimation algorithms", "modified parameters estimation algorithm"
"modified near approximation algorithm" » "modified near approximation algorithms", "modified one approximation algorithm", "modified network approximation algorithm", "modified _ approximation algorithm", "modified seird approximation algorithm", "modified adam approximation 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: (("modified parameters optimization algorithms") or ("modified near approximation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameters optimization algorithms") OR ("modified near approximation algorithm")).
• Removing quotes may allow a broader search: (( modified parameters optimization algorithms ) or ( modified near approximation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameters optimization algorithms") or ("modified near approximation algorithm"))*.
