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