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 invasive evolution algorithm" » "modified invasive solution algorithm", "modified invasive evolutionary algorithm", "modified invasive convolution algorithms", "modified invasive ventilation algorithm", "modified passive evolution algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified invasive evolution algorithm") or ("modified qoe optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified invasive evolution algorithm") OR ("modified qoe optimization algorithm"))*.
• Removing quotes may allow a broader search: (( modified invasive evolution algorithm ) or ( modified qoe optimization algorithm ))*.
