Perhaps you should try some spelling variations:
"modified adaptive optimization algorithms" » "modified adaptive optimisation algorithm", "modified adaptive estimation algorithms", "modified adaptive estimation algorithm", "modified objective optimization algorithms", "modified adaptive quantization algorithms", "modified static optimization algorithms", "modified passive optimization algorithms"
"modified parameter estimates algorithms" » "modified parameter estimation algorithms", "modified parameter estimation algorithm", "modified parameter optimized algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified adaptive optimization algorithms") OR ("modified parameter estimates algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified adaptive optimization algorithms\") OR (\"modified parameter estimates algorithms\"))".
• Removing quotes may allow a broader search: (( modified adaptive optimization algorithms ) OR ( modified parameter estimates algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive optimization algorithms") OR ("modified parameter estimates algorithms"))*.
