Perhaps you should try some spelling variations:
"modified df optimization algorithms" » "modified df optimisation algorithm", "modified df estimation algorithm", "modified df optimized algorithms", "modified _ optimization algorithms", "modified qoe optimization algorithms", "modified _ optimisation algorithms", "modified adam optimization algorithms", "modified bi1 optimization algorithms"
"modified parameters estimation algorithms" » "modified parameter estimation algorithms", "modified parameter estimates algorithms", "modified parameter optimization algorithms", "modified parameters estimation algorithm", "modified parameters optimisation algorithm", "modified parameters 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 df optimization algorithms") OR ("modified parameters estimation algorithms"))~.
• Removing quotes may allow a broader search: (( modified df optimization algorithms ) or ( modified parameters estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified df optimization algorithms") or ("modified parameters estimation algorithms"))*.
