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"
"_ optimized algorithm" » "_ optimizer algorithms"

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