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

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

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