Perhaps you should try some spelling variations:
"_ optimized algorithms" » "_ optimized algorithm", "_ optimizer algorithms", "_ optimization algorithms"
"parameter estimates algorithm" » "parameter estimation algorithm", "parameter estimation algorithms"
"_ optimise algorithms" » "_ optimizer algorithms", "_ optimized algorithm", "_ optimize 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 estimates algorithm") or ((("_ optimized algorithms") or ("_ optimise algorithms"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("parameter estimates algorithm") OR ((("_ optimized algorithms") OR ("_ optimise algorithms")))).
• Removing quotes may allow a broader search: (( parameter estimates algorithm ) or ((( _ optimized algorithms ) or ( _ optimise algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("parameter estimates algorithm") or ((("_ optimized algorithms") or ("_ optimise algorithms"))))*.
