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