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