Perhaps you should try some spelling variations:
"_ optimization algorithm" » "_ optimization algorithms", "_ optimisation algorithm", "_ estimation algorithm"
"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: (((("risk optimized algorithms") OR ("risk optimized algorithm"))) or ("_ optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("risk optimized algorithms") OR ("risk optimized algorithm"))) OR ("_ optimization algorithm")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"risk optimized algorithms\") OR (\"risk optimized algorithm\"))) or (\"_ optimization algorithm\"))".
• Removing quotes may allow a broader search: (((( risk optimized algorithms ) OR ( risk optimized algorithm ))) or ( _ optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("risk optimized algorithms") OR ("risk optimized algorithm"))) or ("_ optimization algorithm"))*.
