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

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("risk optimisation algorithm") OR ("risk estimation algorithm"))) or ("_ optimize algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("risk optimisation algorithm") OR ("risk estimation algorithm"))) OR ("_ optimize algorithms")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"risk optimisation algorithm\") OR (\"risk estimation algorithm\"))) or (\"_ optimize algorithms\"))".
• Removing quotes may allow a broader search: (((( risk optimisation algorithm ) OR ( risk estimation algorithm ))) or ( _ optimize algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("risk optimisation algorithm") OR ("risk estimation algorithm"))) or ("_ optimize algorithms"))*.
