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

Try widening your search to All Fields.

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