Perhaps you should try some spelling variations:
"_ optimisation algorithms" » "_ optimisation algorithm", "_ optimization algorithms", "_ estimation algorithms"
"_ optimization algorithm" » "_ optimization algorithms", "_ optimisation algorithm", "_ estimation algorithm"
"risk optimized algorithm" » "risk optimized algorithms", "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: (("risk optimized algorithm") or ((("_ optimization algorithm") or ("_ optimisation algorithms"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("risk optimized algorithm") OR ((("_ optimization algorithm") OR ("_ optimisation algorithms")))).
• Removing quotes may allow a broader search: (( risk optimized algorithm ) or ((( _ optimization algorithm ) or ( _ optimisation algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("risk optimized algorithm") or ((("_ optimization algorithm") or ("_ optimisation algorithms"))))*.
