Perhaps you should try some spelling variations:
"modified parameter optimization algorithm" » "modified parameter optimization algorithms", "modified parameter optimisation algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithm"
"modified stochastic optimizer algorithmss" » "modified stochastic optimizer algorithms", "modified stochastic optimized algorithms", "modified stochastic optimized algorithm", "modified stochastic 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 stochastic optimizer algorithmss\") OR (\"modified parameter optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( modified stochastic optimizer algorithmss ) OR ( modified parameter optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified stochastic optimizer algorithmss") OR ("modified parameter optimization algorithm"))*.
