Perhaps you should try some spelling variations:
"some optimization algorithmss" » "some optimization algorithms", "some optimisation algorithm", "some estimation algorithms", "some optimization algorithmsss", "some optimisation algorithmss", "some estimation algorithmss", "game optimization algorithmss", "qoe optimization algorithmss", "stage 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.

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