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