Perhaps you should try some spelling variations:
"risk optimisation algorithm" » "risk optimization algorithms", "risk estimation algorithm", "risk estimation algorithms", "_ optimisation algorithm"
"_ optimize algorithmss" » "_ optimized algorithms", "_ optimizer algorithms", "_ optimise algorithmss"
"_ optimized algorithm" » "_ optimized algorithms", "_ optimizer algorithms", "_ optimised algorithm"

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: "((\"risk optimisation algorithm\") OR (((\"_ optimize algorithmss\") OR (\"_ optimized algorithm\"))))~".
• Removing quotes may allow a broader search: (( risk optimisation algorithm ) OR ((( _ optimize algorithmss ) OR ( _ optimized algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("risk optimisation algorithm") OR ((("_ optimize algorithmss") OR ("_ optimized algorithm"))))*.
