Perhaps you should try some spelling variations:
"risk optimisation algorithm" » "risk optimization algorithms", "risk estimation algorithm", "risk estimation algorithms", "_ optimisation algorithm"
"_ optimizer algorithmss" » "_ optimizer algorithms", "_ optimized algorithms", "_ optimized algorithmss", "_ optimize algorithmss", "_ optimise algorithmss"
"qoe optimized algorithm" » "qoe optimized algorithms", "qoe optimizer algorithms", "_ optimized algorithm"

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

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