Perhaps you should try some spelling variations:
"modified parameter optimization algorithms" » "modified parameter optimisation algorithm", "modified parameter estimation algorithms", "modified parameter estimation algorithm", "modified parameters optimization algorithms"
"modified objective optimized algorithmss" » "modified objective optimized algorithms", "modified objective optimized algorithm", "modified objective optimizer algorithms", "modified objective optimal algorithmss", "modified objective optimization algorithmss"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective optimized algorithmss\") OR (\"modified parameter optimization algorithms\"))~".
• Removing quotes may allow a broader search: (( modified objective optimized algorithmss ) OR ( modified parameter optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimized algorithmss") OR ("modified parameter optimization algorithms"))*.
