Perhaps you should try some spelling variations:
"modified parameter optimization algorithms" » "modified parameter estimation algorithms", "modified parameter estimation algorithm", "modified parameter optimized algorithms", "modified parameters optimization algorithms"
"modified stochastic optimisation algorithm" » "modified stochastic optimization algorithm", "modified static optimization algorithm", "modified stochastic configuration algorithm", "modified stochastic estimation algorithm", "modified stochastic estimation algorithms"

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 parameter optimization algorithms\") OR (\"modified stochastic optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified parameter optimization algorithms ) OR ( modified stochastic optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified parameter optimization algorithms") OR ("modified stochastic optimisation algorithm"))*.
