Perhaps you should try some spelling variations:
"modified qoe optimization algorithm" » "modified qoe optimization algorithms", "modified qoe optimisation algorithm", "modified qoe estimation algorithm", "modified game optimization algorithm", "modified _ optimization algorithm", "modified stage optimization algorithm", "modified male optimization algorithm", "modified bi1 optimization algorithm"
"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 optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective solution algorithm") OR ("modified qoe optimization algorithm")).
• Removing quotes may allow a broader search: (( modified objective solution algorithm ) or ( modified qoe optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective solution algorithm") or ("modified qoe optimization algorithm"))*.
