Perhaps you should try some spelling variations:
"robust optimisation algorithm" » "robust optimization algorithms", "robust estimation algorithm", "robust optimization algorithm"
"_ estimation algorithms" » "_ estimation algorithm", "_ optimization algorithms", "_ approximation algorithms"
"_ optimized algorithm" » "_ optimized algorithms", "_ optimizer algorithms"

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("_ estimation algorithms") or ("_ optimized algorithm"))) or ("robust optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("_ estimation algorithms") OR ("_ optimized algorithm"))) OR ("robust optimisation algorithm")).
• Removing quotes may allow a broader search: (((( _ estimation algorithms ) or ( _ optimized algorithm ))) or ( robust optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("_ estimation algorithms") or ("_ optimized algorithm"))) or ("robust optimisation algorithm"))*.
