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