Perhaps you should try some spelling variations:
"_ optimization algorithms" » "_ optimisation algorithm", "_ estimation algorithms", "_ optimizer algorithms"
"_ optimized algorithms" » "_ optimized algorithm", "_ optimizer algorithms"
"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: (((("_ optimized algorithms") OR ("_ optimization algorithms"))) OR ("post estimation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"_ optimized algorithms\") OR (\"_ optimization algorithms\"))) or (\"post estimation algorithm\"))~".
• Removing quotes may allow a broader search: (((( _ optimized algorithms ) OR ( _ optimization algorithms ))) or ( post estimation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ optimized algorithms") OR ("_ optimization algorithms"))) or ("post estimation algorithm"))*.
