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