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