Perhaps you should try some spelling variations:
"risk optimisation algorithm" » "risk optimization algorithms", "risk estimation algorithm", "risk estimation algorithms", "_ optimisation algorithm"
"one optimizer algorithms" » "one optimized algorithms", "one optimized algorithm", "one optimization algorithms"
"_ optimize algorithm" » "_ optimized algorithm", "_ optimized algorithms"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

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