Perhaps you should try some spelling variations:
"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"
"modified objective solution algorithm" » "modified objective evolutionary algorithm", "modified objective allocation algorithm", "modified objective evolution algorithm", "modified objective convolution 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 objective solution algorithm") or ("modified qoe estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective solution algorithm") OR ("modified qoe estimation algorithms")).
• Removing quotes may allow a broader search: (( modified objective solution algorithm ) or ( modified qoe estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective solution algorithm") or ("modified qoe estimation algorithms"))*.
