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"
"_ optimize algorithms" » "_ optimized algorithms", "_ optimizer algorithms", "_ optimized algorithm", "_ optimise algorithms"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"post optimisation algorithm\") OR (((\"_ estimation algorithms\") OR (\"_ optimize algorithms\"))))~".
• Removing quotes may allow a broader search: (( post optimisation algorithm ) OR ((( _ estimation algorithms ) OR ( _ optimize algorithms ))))~.
• Adding a wildcard symbol may retrieve word variants: (("post optimisation algorithm") OR ((("_ estimation algorithms") OR ("_ optimize algorithms"))))*.
