Perhaps you should try some spelling variations:
"modified parameter optimization algorithm" » "modified parameter optimization algorithms", "modified parameter optimisation algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithm"
"modified adaptive estimation algorithmss" » "modified adaptive estimation algorithms", "modified adaptive estimation algorithm", "modified adaptive optimization algorithms", "modified adaptive ventilation algorithmss", "modified quantile estimation algorithmss", "modified adaptive quantization algorithmss", "modified passive estimation algorithmss"

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

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