Perhaps you should try some spelling variations:
"modified objective convolution algorithms" » "modified objective evolution algorithm", "modified objective solution algorithm"
"modified qoe estimation algorithms" » "modified qoe estimation algorithm", "modified qoe optimization algorithms", "modified qoe optimisation algorithm", "modified pose estimation algorithms", "modified _ estimation algorithms", "modified cover estimations algorithms", "modified male estimation algorithms", "modified bi1 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 objective convolution algorithms") OR ("modified qoe estimation algorithms"))~.
• Removing quotes may allow a broader search: (( modified objective convolution algorithms ) or ( modified qoe estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective convolution algorithms") or ("modified qoe estimation algorithms"))*.
