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