Perhaps you should try some spelling variations:
"modified seird approximation algorithm" » "modified seird approximation algorithms", "modified time approximation algorithm", "modified network approximation algorithm", "modified near approximation algorithm"
"modified parameters optimization algorithms" » "modified parameter optimization algorithms", "modified parameter estimation algorithms", "modified parameters optimisation algorithm", "modified parameters estimation algorithms", "modified parameters estimation algorithm"

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 seird approximation algorithm") OR ("modified parameters optimization algorithms"))~.
• Removing quotes may allow a broader search: (( modified seird approximation algorithm ) or ( modified parameters optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified seird approximation algorithm") or ("modified parameters optimization algorithms"))*.
