Perhaps you should try some spelling variations:
"modified notion optimized algorithmss" » "modified notion optimized algorithms", "modified notion optimized algorithm", "modified notion optimizer algorithms"
"modified parameters estimation algorithms" » "modified parameter estimation algorithms", "modified parameter estimates algorithms", "modified parameter optimization algorithms", "modified parameters estimation algorithm", "modified parameters optimization algorithms", "modified parameters optimisation 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 notion optimized algorithmss") OR ("modified parameters estimation algorithms"))~.
• Removing quotes may allow a broader search: (( modified notion optimized algorithmss ) or ( modified parameters estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified notion optimized algorithmss") or ("modified parameters estimation algorithms"))*.
