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