Perhaps you should try some spelling variations:
"risk estimation algorithms" » "risk estimation algorithm", "risk optimization algorithms", "risk optimisation algorithm", "pose estimation algorithms"
"doan optimized algorithm" » "doan optimized algorithms", "doan optimizer algorithms", "doanh optimized algorithm", "toan optimized algorithm", "soan optimized algorithm"
"dan optimized algorithm" » "dan optimized algorithms", "dan optimizer algorithms", "_ optimized algorithm"

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