Perhaps you should try some spelling variations:
"parameter estimation algorithm" » "parameter estimates algorithm", "parameter optimization algorithm"
"_ optimise algorithms" » "_ optimized algorithms", "_ optimizer algorithms", "_ optimize algorithms"
"_ optimized algorithm" » "_ optimized algorithms", "_ optimizer algorithms"

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

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