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