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

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("post optimisation algorithm") OR ((("_ optimizer algorithms") OR ("_ estimation algorithms"))))~.
• Removing quotes may allow a broader search: (( post optimisation algorithm ) or ((( _ optimizer algorithms ) or ( _ estimation algorithms ))))~.
• Adding a wildcard symbol may retrieve word variants: (("post optimisation algorithm") or ((("_ optimizer algorithms") or ("_ estimation algorithms"))))*.
