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