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