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.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("post estimation algorithm") or ("_ optimization algorithms"))) or ("_ optimized algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("post estimation algorithm") OR ("_ optimization algorithms"))) OR ("_ optimized algorithms")).
• Removing quotes may allow a broader search: (((( post estimation algorithm ) or ( _ optimization algorithms ))) or ( _ optimized algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("post estimation algorithm") or ("_ optimization algorithms"))) or ("_ optimized algorithms"))*.
