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