Perhaps you should try some spelling variations:
"post optimization algorithms" » "post optimisation algorithm", "post estimation algorithms", "post estimation algorithm", "robust optimization algorithms", "qoe optimization algorithms", "policy optimization algorithms"
"_ optimized algorithms" » "_ optimized algorithm"
"_ optimizer algorithms" » "_ optimized algorithm", "_ 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 optimization algorithms") OR ((("_ optimized algorithms") OR ("_ optimizer algorithms"))))~.
• Removing quotes may allow a broader search: (( post optimization algorithms ) or ((( _ optimized algorithms ) or ( _ optimizer algorithms ))))~.
• Adding a wildcard symbol may retrieve word variants: (("post optimization algorithms") or ((("_ optimized algorithms") or ("_ optimizer algorithms"))))*.
