Perhaps you should try some spelling variations:
"post optimisation algorithm" » "post optimization algorithms", "post estimation algorithms", "robust optimization algorithm", "_ optimisation algorithm", "qoe optimization algorithm"
"_ optimized algorithm" » "_ optimized algorithms", "_ optimizer algorithms"
"post estimation algorithm" » "pose estimation algorithm", "risk estimation algorithm", "pulses estimation algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("post optimisation algorithm") OR ("post estimation algorithm"))) or ("_ optimized algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("post optimisation algorithm") OR ("post estimation algorithm"))) OR ("_ optimized algorithm")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"post optimisation algorithm\") OR (\"post estimation algorithm\"))) or (\"_ optimized algorithm\"))".
• Removing quotes may allow a broader search: (((( post optimisation algorithm ) OR ( post estimation algorithm ))) or ( _ optimized algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("post optimisation algorithm") OR ("post estimation algorithm"))) or ("_ optimized algorithm"))*.
