Perhaps you should try some spelling variations:
"sphere optimization algorithmss" » "sphere optimisation algorithm", "sphere estimation algorithms", "sphere estimation algorithm", "sphere optimisation algorithms", "sphere estimation algorithmss", "stage optimization algorithmss", "response 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.

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