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