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 write estimation algorithmss" » "modified write estimation algorithms", "modified write estimation algorithm", "modified write optimization algorithms", "modified risk estimation algorithmss", "modified pose estimation algorithmss"

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

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