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

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"_ optimization algorithm\") OR (\"_ optimized algorithm\"))) OR (\"pose estimation algorithms\"))~".
• Removing quotes may allow a broader search: (((( _ optimization algorithm ) OR ( _ optimized algorithm ))) OR ( pose estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ optimization algorithm") OR ("_ optimized algorithm"))) OR ("pose estimation algorithms"))*.
