Perhaps you should try some spelling variations:
"risk optimisation algorithm" » "risk optimization algorithms", "risk estimation algorithm", "risk estimation algorithms", "_ optimisation algorithm"
"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.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("don optimized algorithm") OR ("_ optimized algorithm"))) OR ("risk optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"don optimized algorithm\") OR (\"_ optimized algorithm\"))) or (\"risk optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (((( don optimized algorithm ) OR ( _ optimized algorithm ))) or ( risk optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("don optimized algorithm") OR ("_ optimized algorithm"))) or ("risk optimisation algorithm"))*.
