Perhaps you should try some spelling variations:
"_ optimization algorithms" » "_ optimisation algorithm", "_ estimation algorithms", "_ optimized algorithms"
"_ optimize algorithmss" » "_ optimized algorithms", "_ optimizer algorithms", "_ optimized 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: (((("_ optimize algorithmss") OR ("_ optimization algorithms"))) OR ("post estimation algorithm"))~.
• Removing quotes may allow a broader search: (((( _ optimize algorithmss ) or ( _ optimization algorithms ))) or ( post estimation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ optimize algorithmss") or ("_ optimization algorithms"))) or ("post estimation algorithm"))*.
