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

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameter optimization algorithm") OR ("modified static optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( modified parameter optimization algorithm ) or ( modified static optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified parameter optimization algorithm") or ("modified static optimisation algorithm"))*.
