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