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