Perhaps you should try some spelling variations:
"qoe optimization algorithms" » "qoe optimisation algorithm", "qoe estimation algorithms", "qoe estimation algorithm", "game optimization algorithms", "_ optimization algorithms", "stage optimization algorithms"
"_ convolution algorithms" » "_ evolution algorithm", "_ solution algorithm", "d convolutional algorithms", "_ evolution algorithms", "_ convection algorithms"
"_ solutions algorithm" » "_ solution algorithm", "_ evolution algorithm", "_ evolutionary algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("_ solutions algorithm") or ("_ convolution algorithms"))) or ("qoe optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("_ solutions algorithm") OR ("_ convolution algorithms"))) OR ("qoe optimization algorithms")).
• Removing quotes may allow a broader search: (((( _ solutions algorithm ) or ( _ convolution algorithms ))) or ( qoe optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("_ solutions algorithm") or ("_ convolution algorithms"))) or ("qoe optimization algorithms"))*.
