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