Perhaps you should try some spelling variations:
"modified parameter optimization algorithms" » "modified parameter optimisation algorithm", "modified parameter estimation algorithm", "modified parameter optimized algorithms", "modified parameters optimization algorithms"
"modified quadratic estimation algorithms" » "modified quadratic estimation algorithm", "modified quadratic optimisation algorithm", "modified quadratic approximation algorithms", "modified quadratic optimization algorithms", "modified quantile 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 quadratic estimation algorithms") or ("modified parameter optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified quadratic estimation algorithms") OR ("modified parameter optimization algorithms")).
• Removing quotes may allow a broader search: (( modified quadratic estimation algorithms ) or ( modified parameter optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified quadratic estimation algorithms") or ("modified parameter optimization algorithms"))*.
