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

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