Perhaps you should try some spelling variations:
"_ estimation algorithms" » "_ estimation algorithm", "_ optimization algorithms", "_ optimisation algorithm"
"dose optimized algorithm" » "dose optimized algorithms", "dose optimizer algorithms", "jose optimized algorithm"
"done optimized algorithm" » "done optimized algorithms", "done optimizer algorithms"

You may be able to get more results by adjusting your search query.

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