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