Perhaps you should try some spelling variations:
"_ optimized algorithms" » "_ optimized algorithm", "_ optimizer algorithms", "_ optimization algorithms"
"dose estimation algorithm" » "pose estimation algorithm", "risk estimation algorithm", "cover estimations algorithm"
"post estimation algorithm" » "pose estimation algorithm", "risk estimation algorithm", "pulses estimation algorithm"

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 estimation algorithm") OR ("post estimation algorithm"))) OR ("_ optimized algorithms"))~.
• Removing quotes may allow a broader search: (((( dose estimation algorithm ) or ( post estimation algorithm ))) or ( _ optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dose estimation algorithm") or ("post estimation algorithm"))) or ("_ optimized algorithms"))*.
