Perhaps you should try some spelling variations:
"modified parameters optimization algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameters optimisation algorithm", "modified parameters estimation algorithm", "modified parameters estimation algorithms"
"modified passive optimization algorithms" » "modified passive optimisation algorithm", "modified passive estimation algorithms", "modified passive estimation algorithm", "modified passive optimisation algorithms", "modified passive estimation algorithmss", "modified bayesian optimization algorithms", "modified game optimization algorithms", "modified policy optimization algorithms", "modified adaptive optimization 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 parameters optimization algorithm") OR ("modified passive optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified parameters optimization algorithm\") OR (\"modified passive optimization algorithms\"))".
• Removing quotes may allow a broader search: (( modified parameters optimization algorithm ) OR ( modified passive optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameters optimization algorithm") OR ("modified passive optimization algorithms"))*.
