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