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

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

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