Perhaps you should try some spelling variations:
"modified aging estimation algorithmss" » "modified aging estimation algorithm", "modified aging optimization algorithms", "modified aging estimation algorithms", "modified aging optimization algorithmss", "modified aging optimisation algorithms", "modified lighting estimation algorithmss", "modified risk estimation algorithmss", "modified caging estimation algorithmss"
"modified objective estimation algorithms" » "modified objective estimation algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective allocation algorithms"

Try widening your search to All Fields.

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

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