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