Perhaps you should try some spelling variations:
"modified quadratic optimization algorithmss" » "modified quadratic optimization algorithms", "modified quadratic optimisation algorithm", "modified quadratic estimation algorithms", "modified static optimization algorithmss", "modified quadratic optimization algorithmsss", "modified quadratic optimisation algorithmss", "modified quadratic estimation algorithmss"
"modified parameters optimization algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithms", "modified parameters optimisation algorithm", "modified parameters estimation algorithm"

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

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