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