Perhaps you should try some spelling variations:
"modified parameter optimization algorithms" » "modified parameter optimisation algorithm", "modified parameter estimation algorithm", "modified parameter optimized algorithms", "modified parameters optimization algorithms"
"modified aging estimation algorithms" » "modified aging estimation algorithm", "modified aging optimisation algorithm", "modified aging approximation algorithms", "modified lighting estimation algorithms", "modified risk estimation algorithms", "modified caging estimation algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified aging estimation algorithms") or ("modified parameter optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified aging estimation algorithms") OR ("modified parameter optimization algorithms")).
• Removing quotes may allow a broader search: (( modified aging estimation algorithms ) or ( modified parameter optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified aging estimation algorithms") or ("modified parameter optimization algorithms"))*.
