Perhaps you should try some spelling variations:
"modified parameters optimization algorithmss" » "modified parameters optimisation algorithm", "modified parameters estimation algorithms", "modified parameters estimation algorithm", "modified parameters optimisation algorithms", "modified parameters estimation algorithmss", "modified parameter optimization algorithmss", "modified parameter estimation algorithmss"
"modified bi1 optimization algorithms" » "modified bi1 optimisation algorithm", "modified bi1 estimation algorithms", "modified bi1 estimation algorithm", "modified _ optimization algorithms", "modified qoe optimization algorithms", "modified game optimization algorithms"

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 bi1 optimization algorithms") or ("modified parameters optimization algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified bi1 optimization algorithms") OR ("modified parameters optimization algorithmss")).
• Removing quotes may allow a broader search: (( modified bi1 optimization algorithms ) or ( modified parameters optimization algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified bi1 optimization algorithms") or ("modified parameters optimization algorithmss"))*.
